Thumbnail for Proportionate Impacts of Policing in Chicago | Trina Reynolds-Tyler

Trina Reynolds-Tyler, Data Director, Invisible Institute presents the Technical Vision Talk “(DIS) Proportionate Impacts of Policing in Chicago”. Through public data records requests the Invisible Institute received an unprecedented amount of data related to misconduct records of the Chicago Police Department. Beneath the Surface analyzed these records to uncover patterns of gender based violence at the hands of police. A volunteer team of over 200 community members generated training data for Judy, our nickname for the algorithm which then parsed through narratives of complaints in more than 27,000 misconduct records between 2011 and 2015. We then were able to run a targeted search and identify a range of testimony representing shared experiences; connecting people across time and space. But what proportion is significant enough to constitute as evidence of a deeper issue? How does the universe of information we use to define the numerator or denominator impact our willingness to deepen our questions? Where do we draw the line between significance and meaningfulness when using data science to understand policing in America?

Biography:
Trina Reynolds-Tyler is the Data Director at the Invisible Institute, an abolitionist, and a native of south side Chicago. She leads Beneath the Surface, a project employing machine learning to identify gender based violence at the hands of Chicago police.

Keynote: A Sparkle in the Dark The Outlandish Quest for Dark Matter | Maria Elena Monzani

Thumbnail for Keynote: A Sparkle in the Dark The Outlandish Quest for Dark Matter | Maria Elena Monzani

Maria Elena Monzani, Lead Scientist, SLAC National Accelerator Laboratory and Kavli Institute for Particle Astrophysics and Cosmology, Stanford University leads the Keynote Address “A Sparkle in the Dark: The Outlandish Quest for Dark Matter.” The nature and origin of dark matter are among the most compelling mysteries of contemporary science. There is strong evidence for dark matter from its role in shaping the galaxies and galaxy clusters that we observe in the universe. Still, for over three decades, physicists have been trying to detect the dark matter particles themselves with little success.

This talk will describe the leading effort in that search, the LUX-ZEPLIN (LZ) detector. LZ is an instrument that is superlative in many ways. It consists of 10 tons of liquified xenon gas, maintained at almost atomic purity and stored in a refrigerated titanium cylinder a mile underground in a former gold mine in Lead, South Dakota.

During its science run, LZ is projected to accumulate a massive dataset, consisting of many petabytes of data and recording several billions of particle interactions, only a handful of which might be produced by potential dark matter candidates (if nature cooperates). Identifying the dark matter signals in this amassment of data represents an extreme “needle in a haystack” problem, and requires leveraging advanced detector design and stat-of-the art machine learning algorithms. The talk will present some of the challenges in constructing this large-scale underground experiment and interpreting its data, along with the prospects LZ presents for finally discovering the dark matter particle, and recently-released results from its initial search for new physics.

Biography:
Maria Elena Monzani is a dark matter data wrangler. Her research field is Astroparticle physics, which focuses on topics at the intersection between particle physics and astrophysics/cosmology, using the tools of data intensive science. She received a dual PhD from University of Milano and University of Paris 7, performing research with the Borexino experiment that measured neutrinos produced by the Sun. She then held a postdoctoral position at Columbia University before joining SLAC in 2007 to work on the Fermi Gamma-ray Space Telescope.

Optimization in the loop machine learning for energy and climate | Priya Donti

Thumbnail for Optimization in the loop machine learning for energy and climate | Priya Donti

Priya Donti, Co-Founder and Executive Director, Climate Change AI presents Technical Vision Talk “Optimization-in-the-loop machine learning for energy and climate”. Addressing climate change will require concerted action across society, including the development of innovative technologies. While machine learning (ML) methods have the potential to play an important role, these methods often struggle to contend with the physics, hard constraints, and complex decision-making processes that are inherent to many climate and energy problems. To address these limitations, I present the framework of ‚Äúoptimization-in-the-loop ML,‚Äù and show how it can enable the design of ML models that explicitly capture relevant constraints and decision-making processes. For instance, this framework can be used to design learning-based controllers that provably enforce the stability criteria or operational constraints associated with the systems in which they operate. It can also enable the design of task-based learning procedures that are cognizant of the downstream decision-making processes for which a model‚Äôs outputs will be used. By significantly improving performance and preventing critical failures, such techniques can unlock the potential of ML for operating low-carbon power grids, improving energy efficiency in buildings, and addressing other high-impact problems of relevance to climate action.

Making Biosignal Interfaces Accessible | Momona Yamagami

Thumbnail for Making Biosignal Interfaces Accessible | Momona Yamagami

Momona Yamagami, Incoming Assistant Professor, Electrical and Computer Engineering, Rice University presents the Technical Vision Talk on “Making Biosignal Interfaces Accessible”. Biosignal interfaces that use electromyography sensors, accelerometers, and other biosignals as inputs provide promise to improve accessibility for people with disabilities. However, generalized models that are not personalized to the individual‚Äôs abilities, body sizes, and skin tones may not perform well. Individualized interfaces that are personalized to the individual and their abilities could significantly enhance accessibility.

In this talk, I discuss how continuous (i.e., 2-dimensional trajectory-tracking) and discrete (i.e., gesture) electromyography (EMG) interfaces can be personalized to the individual. For the continuous task, we used methods from game theory to iteratively optimize a linear model that mapped EMG input to cursor position. For the discrete task, we developed a dataset of participants with and without disabilities performing gestures that are accessible to them. As biosignal interfaces become more commonly available, it is important to ensure that such interfaces have high performance across a wide spectrum of users.

Biography:
Momona will be an Assistant Professor at Rice University Electrical & Computer Engineering starting summer 2023 as part of the Digital Health Initiative. Her research focuses on modeling and enhancing human-machine interaction (HMI) to support accessibility and health using biosignals and control theory applied to the field of HCI (human-computer interaction). I am currently a CREATE postdoctoral scholar at the University of Washington in Seattle, WA, advised by Prof. Jennifer Mankoff.

Momona’s dissertation research leveraged control theory methods to model and enhance continuous HMIs and explore biosignals like electromyography (EMG) as accessible machine inputs for people with and without disabilities. Her current research interests include how multi-input biosignals can improve HMI accessibility for new and emerging technology like virtual reality and support the health of people with disabilities.

Introduction to Linear Regression | Laura Lyman

Thumbnail for Introduction to Linear Regression | Laura Lyman

Linear regression is a fundamental tool in statistics and data science for modeling the relationship between different parameters. It can be used for prediction, forecasting and error reduction by fitting a predictive model between a response variable and a collection of explanatory variables based on an observed data set. Through linear regression analysis, we can quantify the strength of the linear relationship between the response and different explanatory variables, and we can identify parameters that may contain redundant information.

This workshop introduces the basics of simple and multiple linear regression. We will present both mathematical theory and applications in the context of real data sets — ranging from survey results collected by the US National Center for Health Statistics (NHANES), to real estate listings in Sacramento, CA. After the talk, the R code used will be provided, so attendees can revisit examples of how to apply this foundational modeling method.

This workshop was conducted by Laura Lyman, Instructor of Mathematics, Statistics, and Computer Science (MSCS) at Macalester College

Introduction to Precision Medicine: From Statistics to Society

Thumbnail for Introduction to Precision Medicine: From Statistics to Society

Precision medicine aims to learn from data how to match the right treatment to the right person at the right time. One common goal in precision medicine is the estimation of optimal dynamic treatment regimens (DTRs), sequences of decision rules that recommend treatments to patients in a way that, if followed, would optimize outcomes for each individual and overall, in the targeted population. In this presentation, we will describe how the precision medicine framework formalizes sequential clinical decision-making and briefly review a subset of the most popular strategies for learning optimal dynamic treatment regimes. We will then invite the workshop group to ideate and discuss the critical opportunities and challenges for the translation of DTRs to clinical and community care, the role of stakeholder engagement and cross-disciplinary collaboration, and considerations for evaluating DTRs in practice.

This workshop was conducted by Nikki Freeman and Anna Kahkoska from the University of North Carolina at Chapel Hill.

Earth observation & machine learning for agroecological applications

Thumbnail for Earth observation & machine learning for agroecological applications

The usage of machine learning (ML) has been growing exponentially. Its significant power in generalization and a large amount of available data make machine learning indispensable. In parallel, humanity is focused more than ever on space exploration, developing cutting-edge Earth Observation (EO) technology. Have you ever wondered how these two can be combined?

One domain that can be greatly benefited from this coalition is agriculture. With climate change and population rise, maintaining natural ecosystems while enhancing agricultural productivity and supporting farmers is of primary importance. In this sense, ML and EO technologies are the key enablers in developing actionable recommendations for farmers and policymakers to achieve resilient agriculture. In this workshop, we discuss the usage of ML for EO-related applications, focusing on agriculture and ecosystem services. We will present two applications of how ML bridges the gap between scientific knowledge and actionable advice for farmers and policymakers. The first application will consist of a predictive ML model related to the occurrence of pests in cotton fields. The second application will showcase the combination of a geographical model and an ML algorithm to identify the local-specific contribution of agricultural management to ecosystem services. For both applications, there will be live demonstrations using Python and R. By the end of this workshop, we hope you will be acquainted with establishing the link between machine learning, earth observation, and sustainable agriculture. Wishing you a fruitful exploration of this field having provided you with the necessary tools to start your journey!

This workshop was conducted by Roxanne Suzette Lorilla and Ornela Nanushi from the National Observatory of Athens.

Mitigating Bias in Machine Learning and Data Science

Photographs of Menglin Cao, Leda Braga, and Susan Athey. With WiDS branded illustrations in the background.

​AI and machine learning are increasingly being used across industry and government to make decisions impacting many parts of our lives. These technologies could determine who gets a job interview, what products are advertised to different audiences, or what government resources are allocated to different populations. Bias can become embedded in the development of AI systems either through the data and/or the development and evaluation of algorithms. This can result in inaccurate predictions that can significantly impact people’s lives. Several WiDS talks describe how bias in machine learning can impact everything from online ads to search recommendations to bus routes.

Counterfactual Explanations: The Future of Explainable AI | Aviv Ben Arie

Thumbnail for Counterfactual Explanations: The Future of Explainable AI | Aviv Ben Arie

As data scientists, the ability to understand our models’ decisions is important, especially for models that could have a high impact on people’s lives. This may pose several challenges, as most models used in the industry are not inherently explainable. Today, the most popular explainability methods are SHAP (SHapley Additive exPlanations) and LIME (Local Interpretable Model-Agnostic Explanation). Each method offers convenient APIs, backed by solid mathematical foundations, but falls short in intuitiveness and actionability.

In this workshop/article, I will introduce a relatively new model explanation method – Counterfactual Explanations (CFs). CFs are explanations based on minimal changes to a model’s input features that lead the model to output a different (mostly opposite) predicted class. CFs have been shown to be more intuitive for humans to comprehend and provide actionable feedback, compared to traditionalSHAP and LIME methods. I will review the challenges in this novel field (such as how to ensure that the CF proposes changes which are feasible), provide a birds-eye view of the latest research and give my perspective, based on my research in collaboration with Tel Aviv University, on the various aspects in which CFs can transform the way data science practitioners understand their ML models.

Predicting customer choice: A case study on integrating AI within a discrete choice model | Kathryn

Thumbnail for Predicting customer choice: A case study on integrating AI within a discrete choice model | Kathryn

Neural networks have been widely celebrated for their power to solve difficult problems across a number of domains. We explore an approach for leveraging this technology within a statistical model of customer choice. Conjoint-based choice models are used to support many high-value decisions at GM. In particular, we test whether using a neural network to model customer utility enables us to better capture non-compensatory behavior (i.e., decision rules where customers only consider products that meet acceptable criteria) in the context of conjoint tasks. We find the neural network can improve hold-out conjoint prediction accuracy for synthetic respondents exhibiting non-compensatory behavior only when trained on very large conjoint data sets. Given the limited amount of training data (conjoint responses) available in practice, a mixed logit choice model with a traditional linear utility function outperforms the choice model with the embedded neural network.

Demystifying Data Pre-processing & Data Wrangling for Data Science | Pariza Kamboj

Thumbnail for Demystifying Data Pre-processing & Data Wrangling for Data Science | Pariza Kamboj

In the current era, Data Science is rapidly evolving and proving very decisive in ERP (Enterprise Resource Planning). The dataset required for building the analytical model using data science, is collected from various sources such as Government, Academic, Web Scraping, API’s, Databases, Files, Sensors and many more. We cannot use such real-world data for analysis process directly because it is often inconsistent, incomplete, and more likely to contain bulk errors. We often hear the phrase “garbage in, garbage out”. Dirty data or messy data riddled with inaccuracies and errors, result in a bad/improperly trained model which in turn might result in poor business decisions and sometimes even hazardous to the domain. Any powerful algorithm is failed in providing correct analysis when applied to bad data. Therefore, data must be curated, cleaned and refined to be used in data science and products based on data science. To perform these tasks, “Data Preparation” is required which includes two methods that are: Data Pre-processing, and Data Wrangling. Most data scientists spend the majority of their time in data preparation.

Thumbnail for Keynote: The Rigorous and Human Life of Data | Cecilia Aragon | University of Washington

Cecilia Aragon, Professor, Human Centered Design & Engineering, University of Washington, presents a Keynote at the WiDS Worldwide conference.

Very often, the words ‘rigorous’ and ‘human-centered’ have been used as opposites in technical fields, with the implication that a focus on human aspects makes science ‘soft’ or ‘insufficiently technical’. This is a false dichotomy that Cecilia will argue in this talk.

While extraordinary advances in our ability to collect, analyze, and interpret vast amounts of data have been transforming the fundamental nature of data science, the human aspects of data science, including how to support scientific creativity and human insight, how to address ethical concerns, and the consideration of societal impacts, have been less studied. Yet these human issues are becoming increasingly vital to the future of data science. Cecilia will reflect on a 30-year career in data science in industry, government, and academia, discuss what it means for data science to be both rigorous and human-centered, and speculate upon future directions for data science.

Beyond Bias: Algorithmic Unfairness, Infrastructure and Genealogies of Data | Alex Hanna | WiDS 2022

Thumbnail for Beyond Bias: Algorithmic Unfairness

Alex Hanna, Director of Research, DAIR Institute, presents a Technical Vision Talk at the WiDS Worldwide conference.

Problems of algorithmic bias are often framed in terms of lack of representative data or formal fairness optimization constraints to be applied to automated decision-making systems. However, these discussions sidestep deeper issues with data used in AI, including problematic categorizations and the extractive logics of crowd work and data mining.

In this talk Alex will make two interventions: first by reframing of data as a form of infrastructure, and as such, implicating politics and power in the construction of datasets; and secondly discussing the development of a research program around the genealogy of datasets used in machine learning and AI systems.

Nandi Leslie, Engineering Fellow at Raytheon Technologies, presents a Technical Vision Talk at the WiDS Worldwide conference.

For nearly 40 years, computer scientists and engineers have been concerned with the problem of monitoring networks for unauthorized activities. More recently, anomaly-based intrusion detection systems have been developed to protect enterprise and mobile networks from such attacks. Nonetheless, in-vehicle networks remain vulnerable to a variety of remote attacks that erode information confidentiality, availability, and integrity.

In this talk, Nandi develops an ensemble hierarchical agglomerative clustering (E-HAC) algorithm for detecting remote attacks on the CAN bus. E-HAC is an ensemble learning approach over multiple clustering algorithms with different linkages and pairwise distances between observations. In addition, she presents prediction performance results for a dataset consisting of CAN bus and remote attack network traffic to demonstrate the effectiveness of this E-HAC algorithm.

AI & Neuroscience: Combining Real-Time Brain Imaging and Machine Learning | Romy Lorenz

Thumbnail for AI & Neuroscience: Combining Real-Time Brain Imaging and Machine Learning | Romy Lorenz

Cognitive neuroscientists are often interested in broad research questions, yet use overly narrow experimental designs by considering only a small subset of possible experimental conditions. This limits the generalizability and reproducibility of many research findings. In this workshop, I present an alternative approach, “The AI Neuroscientist”, that resolves these problems by combining real-time brain imaging with a branch of machine learning, Bayesian optimization. Neuroadaptive Bayesian optimization is an active sampling approach that allows to intelligently search through large experiment spaces with the aim to optimize an unknown objective function. It thus provides a powerful strategy to efficiently explore many more experimental conditions than is currently possible with standard brain imaging methodology. Alongside methodological details on non-parametric Bayesian optimization using Gaussian process regression, I will present results from a clinical study where we applied the method to map cognitive dysfunction in stroke patients. Our results demonstrate that this technique is both feasible and robust also for clinical cohorts. Moreover, our study highlights the importance of moving beyond traditional ‘one-size-fits-all’ approaches where patients are treated as one group. Our approach can be combined with brain stimulation or other therapeutics, thereby opening new avenues for precision medicine targeting a diverse range of neurological and psychiatric conditions.

In this workshop, we focus on temporal domain from perspective of both traditional recommender systems and deep neural networks. We first start with the classic latent factor model. We introduce temporal dynamics in the latent factor model and show how this improves performance. We then move into sequential modelling using deep neural networks by presenting state-of-the-art in the field and discuss the advantages and disadvantages.

Machine Learning: A New Approach to Drug Discovery | Daphne Koller | WiDS 2020

Thumbnail for Machine Learning: A New Approach to Drug Discovery | Daphne Koller | WiDS 2020

Daphne Koller, CEO and Founder at insitro delivers a Keynote presentation at WiDS Stanford University on March 2, 2020:

Modern medicine has given us effective tools to treat some of the most significant and burdensome diseases. At the same time, it is becoming consistently more challenging to develop new therapeutics: clinical trial success rates hover around the mid-single-digit range; the pre-tax R&D cost to develop a new drug (once failures are incorporated) is estimated to be greater than $2.5B; and the rate of return on drug development investment has been decreasing linearly year by year, and some analyses estimate that it will hit 0% before 2020. A key contributor to this trend is that the drug development process involves multiple steps, each of which involves a complex and protracted experiment that often fails.

We believe that, for many of these phases, it is possible to develop machine learning models to help predict the outcome of these experiments, and that those models, while inevitably imperfect, can outperform predictions based on traditional heuristics. The key will be to train powerful ML techniques on sufficient amounts of high-quality, relevant data.

To achieve this goal, we are bringing together cutting edge methods in functional genomics and lab automation to build a bio-data factory that can produce relevant biological data at scale, allowing us to create large, high-quality datasets that enable the development of novel ML models. Our first goal is to engineer in vitro models of human disease that, via the use of appropriate ML models, are able to provide good predictions regarding the effect of interventions on human clinical phenotypes. Our ultimate goal is to develop a new approach to drug development that uses high-quality data and ML models to design novel, safe, and effective therapies that help more people, faster, and at a lower cost.

In the age of artificial intelligence (AI) and data science, workers will spend more time on activities that require social and emotional skills, creativity, high-level cognitive capabilities and other skills that are relatively hard to automate.

There is growing evidence of the importance of a high emotional quotient (EQ) as a predictor of success and organizational performance. In this talk, Professor Liu will share insights gained from her personal career journey and describe initiatives being undertaken in the College of Engineering at the University of California, Berkeley to cultivate EQ in their students and to advance equity and inclusion, toward a brighter future for all.

Rama Akkiraju, IBM Fellow and Director of AI Operations at IBM, delivers a Technical Vision Talk at WiDS Stanford University on March 2, 2020:

AI applications are proliferating in consumer and business domains these days around the world. Have you ever wondered how Siri, Google Home, Google Maps or Amazon Echo speaks to users in different countries in their local languages? How does an automated customer support chat bot that you are speaking with or texting with speak or understand your local language to resolve your problems? AI models that power these applications have to speak the language of the user and the language of the business for them to be useful and relevant. Polyglot AI is not magic just the way AI itself is not magic! It takes a lot of hard work to teach AI to understand and speak new languages. In this talk, I’ll take you through some behind the scenes hard work to build multilingual natural language processing systems that enables AI to speak multiple languages.

Thumbnail for Building Water Security From the Bottom Up by Leveraging Big Data | Newsha Ajami | WiDS 2020

Newsha Ajami, Director of Urban Water Policy at Stanford University, delivers a Technical Vision Talk at WiDS Stanford University on March 2, 2020

Access to safe and reliable water is the foundation of social, economic, and environmental wellbeing, however it is being threatened by impacts of climate change, environmental degradation, population growth, and aging infrastructure. According to the United Nations water security is one of the 21st century’s greatest challenges. Our current water infrastructure networks have been designed and governed under the assumption of abundance and stationarity, believing that by harnessing nature we could deliver unlimited amounts of water to various sectors. There was limited accounting for human dynamics uncertainties in managing these complex networks. Building climate-resilient and sustainable water systems under such structural and environmental pressures requires an integrated and holistic approach that would better represent the interlinks among science/engineering, society, and policy.

While this is easier said than done, some of the emerging data sources from digital platforms, online aggregators, social media, and measurement technologies (e.g. sensors and remotely sensed data), combined with improved computing power, are offering new opportunities to unfold and better define the new frontiers of water sustainability and resiliency. In this talk I will share a portfolio of innovative water management tools that harness new data sources to assess both evolving water demand trends and modern supply regimes to achieve water security.

Customer diversity plays important role for Intuit in product design

Diversity applies to more than just the makeup of any given workforce. It’s become especially important in understanding how products will be received by customers.

Intuit Inc. develops and sells accounting and tax preparation software, and its QuickBooks product serves more than 2.5 million users worldwide. With a customer base that large, being attuned to the diverse needs of its subscribers has become a key ingredient in the company’s overall success.

“We serve consumers, small businesses, and the self-employed,” said Nhung Ho (pictured), director of data science at Intuit. “The diversity of our customers mirrors the general population. You need to bring in diverse perspectives so you can build the best products possible because the people who are using those products come from a diverse background as well.”

Ho spoke with Sonia Tagare, host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Women in Data Science conference in Stanford, California. They discussed how testing in the cloud has helped Intuit build products for a highly diverse customer base and ways the company can tailor its solutions for specific users.

Cloud enhances testing
One way to know how users might respond to newly introduced products is through a process known as A/B testing. It’s a process of showing two variants of a product to different groups of people to determine which will achieve better results.

Before the cloud, testing was usually limited to once a year — just before a new product would ship. Times have changed.

“Now that we’re in the cloud, it allows us to test continuously via A/B testing,” Ho explained. “You turn what was once a one-time change-management process to one that’s distributed throughout the entire year. At any one time we’re running hundreds of tests to make sure we’re shipping the best things for our customers.”

This process has also allowed Intuit to personalize products in ways that weren’t often possible before.

“We have enough data and we have enough compute where we can build a model tailored just for you,” Ho said. “That means I can help a cupcake shop owner actually manage her cash flow to help her succeed. That’s really powerful, and that’s where data science is headed.”

LinkedIn pursues its vision to leverage data for global economic opportunity

It would be a mistake to simply characterize LinkedIn Corp. as merely a job or networking website.

With 660 million users, LinkedIn has the ability to leverage a tremendous amount of data in ways that go far beyond the latest job switch or promotion. The field of data science is helping it transform economic structures on a worldwide scale.

“Everybody can benefit from better data and better data access,” said Ya Xu (pictured), head of data science at LinkedIn. “We truly believe in the vision that we are working towards, which is creating economic opportunity for every member of the global workforce.”

Xu spoke with Sonia Tagare, host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Women in Data Science conference in Stanford, California. They discussed using data responsibly, the importance of diversity, and advice for women seeking a career in the data science field.

Data privacy is fundamental
Speaking at the WiDS conference this week, Xu addressed ways that responsible data can create global opportunity. Data privacy and diversity are fundamental components of that strategy, according to Xu.

“The fundamental thing that we have to start with is to be able to preserve the privacy of our members,” Xu said. “If you have a diverse team that is a representation of the customers you are serving, then you are able to come up with better features that are able to serve the needs of a population. That’s just the right thing to do.”

In her role as a data science leader for LinkedIn, Xu has advice for other women who may be seeking to follow their own careers in the field.

“Just have that ‘can do’ attitude,” Xu said. “We’re not any less than a man, and there are certainly many strong and talented women that we have in the field. Don’t let people’s’ perceptions or biases around you bring you down.”

Q&A: Coursera uses student skill tracking data to help companies create a more diverse workforce

Distance learning has been around since the late 18th century, when students received assignments via mail, completed them, and sent them back for grading. Today, massive open online courses, known as MOOC’s, can have hundreds of thousands of students. Some of the most popular free lectures on YouTube, such as Stanford University’s lecture on Einstein’s theory of relativity, have millions of views.

MOOC’s started to gain popularity back in 2012, when Stanford professor’s Daphne Koller and Andrew Ng decided to make their lectures available online. Those courses became the foundation for Coursera Inc., which today has around 50 million students and is the world’s largest platform for higher education.

Emily Glassberg Sands (pictured), senior director of data science at Coursera, joined Sonia Tagare, host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Women in Data Science conference in Stanford, California. They discussed the changes happening in MOOC structure, and how tracking student skill data can help companies hire a more diverse workforce.

[Editor’s note: The following content has been condensed for clarity.]

How has Coursera changed from when it started in 2012?

Glassberg Sands: It’s evolved a lot. We’ve moved from partnering exclusively with universities to recognizing that a lot of the most important education for folks in the labor market is being taught within companies. So, we’ve expanded to including education that’s provided not just by top institutions like Stanford, but also by top institutions that are companies like Amazon and Google.

The second big change is we’ve recognized that while for many learners and individual course or an MOOC is sufficient, some learners need access to a full degree — a diploma bearing credential. We now have 14 degrees live on the platform, including master’s degrees in computer science and data science.

The third major change is that we launched Coursera enterprise, which is about providing learning content through employers and through governments so we can reach a wider swath of individuals who might not be able to afford it themselves.

Could you explain how Coursera use data science to track individual user preferences and user behavior?

Glassberg Sands: We personalize throughout the learner journey. So, in discovery up-front when you first join the platform, we ask: What’s your career goal? What role are you in today? And then we help you find the right content to close the gap.

As you’re moving through courses, we predict whether or not you need some additional support. So, we identify for each individual what type of human touch might they need and we serve up to support staff recommendations for who they should reach out to, whether it’s a counselor reaching out to a degree student who hasn’t logged in for a while or a teaching assistant reaching out to a degree student who’s struggling with an assignment. Data really powers all of that, understanding someone’s goals, their backgrounds, the content that’s going to close the gap, as well as understanding where they need additional support and what type of help we can provide.

Tell us about Coursera’s latest data products.

Glassberg Sands: We’ve launched three data products over the last couple of years. The first is predicting when learners are going to need additional nudges and intervening in fully automated ways to get them back on track.

The second is about identifying learners who need human support and serving up really easily interpretable insights to support staff so they can reach out to the right learner with the right help.

Then the third is a little bit different. It’s about once learners are out in the labor market, how can they credibly signal what they know so that they can be rewarded for that learning on the job. And this is a product called skill scoring, where we’re actually measuring what skills each learner has up to what level so I can, for example, compare that to the skills required in my target career or show it to my employer so I can be rewarded for what I know.

That would be really helpful when people are creating resumes, by ranking the level of skills that they have.

Creating resilient, sustainable water supplies means flipping the management paradigm

Humanity is dependent on water, but modern methods have major flaws. Perhaps today’s technology can help.

For millennium, settlements were centered on water supplies and drought signaled disaster. The Egyptians were the first to manage the critical resource; diverting the Nile flood waters using a series of dams and canals in a major irrigation project that turned a seasonal lake into a water reservoir. The concept was exploited to great success by the Romans; the empire became known for its sophisticated aqueduct system that transported water from rural areas to towns.

What was basically the same idea continued into the twentieth century, and dams and reservoirs are still being built to supply our ever-expanding cities. However, despite being the definitive method for water management for most of human civilization, the top-down model has a major flaw.

“People were not part of the loop. The way that they behaved, their decision-making process, what they use, how they use it, wasn’t necessarily part of the process,” said Newsha Ajami (pictured), director of urban water infrastructure and policy at Stanford University’s Water in the West program. “We assume there’s enough water out there to bring water to people and they can do whatever they want with it.”

As well as Water in the West, Ajami works with Stanford-based National Science Foundation Engineering Research Center’s Re-Inventing the Nation’s Urban Water Infrastructure (ReNUWIt), and is in her second term serving on the San Francisco Bay Regional Water Quality Control Board.

Ajami spoke with Sonia Tagare, host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Women in Data Science conference in Stanford, California. They discussed how Ajami is working to bridge the gap between science and policy in water management, building solutions for water resilient cities, and changing the traditional top-down water management model to a more collaborative bottom-up approach.

This week theCUBE spotlights Newsha Ajami in its Women in Tech feature

Girls and boys are equal in STEM
Ajami was born in Tehran, Iran, to a family of engineers. She was encouraged in her love of math and problem solving and recalls spending hours building Legos and playing mathematical games. She credits her mother with being her biggest fan and mentor and is quoted as saying she was “raised gender blind” and taught “to be fearless, open-minded, and resilient.”

Thanks to her family’s recognition and support of her math and science abilities, Ajami attended Amirkabir University of Technology, one of Iran’s top universities. She graduated with a bachelor of science in civil and environmental engineering.

“We are all equal. Our brains are all made the same way. It doesn’t matter what’s on the surface,” is Ajami’s message to those who want to study for a career in math, science, technology or engineering. “I encourage all girls to study hard and not get discouraged. Fail as many times as you can, because failing is an opportunity to become more resilient and learn how to grow,” she said.

After living in Tehran during the Iran-Iraq war, Ajami personally understands how water shortages can affect daily life for a city’s inhabitants. “Demand management and public awareness was a centerpiece in dealing with scarcity,” she said, recalling how the experience inspired her to focus on sustainable resource management.

Ajami moved to the United States to attend graduate school at George Washington University, but soon switched to the University of Arizona’s hydrology and water resources program to study under Soroosh Sorooshian, founding director of the university’s National Science Foundation center on sustainability of semi-arid hydrology and riparian areas. “It was one of the best decisions I made,” she said

Her time at the University of Arizona inspired a love for public policy and applied interdisciplinary research, and after obtaining her master’s degree, Ajami followed Sorooshian to the University of California at Irvine to pursue a doctorate in civil and environmental engineering. She continued her education with post-doc research at the University of California at Berkeley, in “the impacts of hydrological uncertainty on efficient and sustainable water resources management and planning.”

AI works to slash drug development costs as technology and biology join forces to defeat Eroom’s Law

The convergence of previously discrete fields is a hallmark of the digital era. Remember the divide between development and operations teams? That gap vanished into the cloud, as DevOps became the new way of working.

Now technology is becoming incorporated into other disciplines. In the 1990s, quantitative biology took a leap from a descriptive science to gene sequencing, thanks to technology such as microarrays. At the same time, big data was revolutionizing information technology.

“What I think is coming now, 30 years later, is the convergence of those two fields into one field that I like to think of as digital biology,” said Daphne Koller (pictured), founder and chief executive officer of Insitro Inc.

Koller spoke with Sonia Tagare, host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Women in Data Science conference in Stanford, California. They discussed how applying machine-learning techniques to traditionally biological research fields — such as drug research — could bring down the costs of medicine.

Applying ML models to drug development
Measuring biology has taken on new levels of detail, fidelity and scale thanks to new technology, according to Koller. Artificial intelligence and machine learning allow scientists to interpret what they are seeing and engineer new solutions that “will have implications in biomaterials, in energy, in the environment, in agriculture, and I think also in human health,” Koller said.

One of the biggest problems in the health field is the negative trend in number of drugs approved versus dollars spent on research. This is known as Eroom’s Law, because it is the opposite of Moore’s Law.

“Despite many important advancements, the costs just keep going up and up and up,” Koller said.

Approach problems with diversity
Machine learning could hold the key to breaking this trend, but it requires a cross-discipline approach, according to Koller. “One needs to really build a culture of people who work together from different disciplines, each bringing their own insights and their own ideas into the mix,” she said.

The team she has created at Insitro is half life scientists and half machine learning and data science experts.

“They start from the very beginning to understand what are the problems that one could solve together: How do you design the experiment? How do you build the model? And how do you drive insights that can help us make better medicines for people?” she said.

Using a data-driven approach, collecting and analyzing huge amounts of data will reveal new hypotheses, according to Koller.

“Hopefully, we’ll be able to create enough data and apply machine learning to address key bottlenecks in the drug discovery and development process,” she said. “[Then] we can bring better drugs to people, and we can do it faster and, hopefully, at much lower cost.”

Cynthia Dwork, Gordon McKay Professor of Computer Science at Harvard University.

Differential privacy is a mathematically rigorous definition of privacy tailored to statistical analysis of large datasets. Differentially private systems simultaneously provide useful statistics to the well-intentioned data analyst and strong protection against arbitrarily powerful adversarial system users — without needing to distinguish between the two. Differentially private systems “don’t care” what the adversary knows, now or in the future. Finally, differentially private systems can rigorously bound and control the cumulative privacy loss that accrues over many interactions with the confidential data. These unique properties, together with the abundance of auxiliary data sources and the ease with which they can be deployed by a privacy adversary, led the US Census Bureau to adopt differential privacy as the disclosure avoidance methodology of the 2020 decennial census.

This talk will motivate the definition of differential privacy, describe some of the techniques to be used in the 2020 census, and explain some of the utility gains over previous methods and the sense in which differential privacy provides a best-possible solution. Finally, the talk will highlight a few of the many remaining challenges.

Hilary Parker, Data Scientist, Stitchfix

Data is the lifeblood of every organization. Whatever our job title, each of us uses data to get our job done — from observing a running system to improving performance to building a machine-learned model. This talk is about approaches and techniques to collect the most useful data we can, analyze it in a scientific way, and use it most effectively to drive actions and decisions.

Is using data effectively an art or a science? It is both. Theart‚Äù helps us decide theright‚Äù way to approach an analysis or an algorithm. Thescience‚Äù applies statistical rigor to our inferences. But with only the art and the science, we miss something critically important. In this talk, I suggest that, beyond both art and science, the fundamental questions we need to ask of our data should be informed by the field of design and design thinking. Every designer needs to understand their intended user, whether they are designing a physical object, experimenting on a recommendation system, or making a launch decision about a product. That focus on the why — instead of just the how and the what — takes us to the next level.

This talk with leave you with actionable insights about how to apply the lens of design thinking to help you use data more effectively in your everyday job.

Anima Anandkumar, Professor of Computing and Mathematical Sciences at CalTech and Director of Research in Machine Learning, NVIDIA.

Standard deep-learning algorithms are based on a function-fitting approach that do not exploit any domain knowledge or constraints. This makes them unsuitable in applications that have limited data or require safety or stability guarantees, such as robotics. By infusing structure and physics into deep-learning algorithms, we can overcome these limitations. There are several ways to do this. For instance, we use tensorized neural networks to encode multidimensional data and higher-order correlations. We infuse symbolic expressions into deep learning to obtain strong generalization. We utilize spectral normalization of neural networks to guarantee stability and apply it to stable landing of quadrotor drones. These instances demonstrate that building structure into ML algorithms can lead to significant gains.

Timnit Gebru, Research Scientist on the Ethical AI Team, Google

Automated decision making tools are currently used in high stakes scenarios. From natural language processing tools used to automatically determine one’s suitability for a job, to health diagnostic systems trained to determine a patient’s outcome, machine learning models are used to make decisions that can have serious consequences on people’s lives. In spite of the consequential nature of these use cases, vendors of such models are not required to perform specific tests showing the suitability of their models for a given task. Nor are they required to provide documentation describing the characteristics of their models, or disclose the results of algorithmic audits to ensure that certain groups are not unfairly treated.

I will show some examples to examine the dire consequences of basing decisions entirely on machine learning based systems, and discuss recent work on auditing and exposing the gender and skin tone bias found in commercial gender classification systems. I will end with the concept of an AI datasheet to standardize information for datasets and pre-trained models, in order to push the field as a whole towards transparency and accountability.

These tables may have columns of different (sometimes, non-numeric) types, and often have many missing entries. In this talk, we discuss how to use low rank models to analyze these big messy data sets.

Low rank models perform well across a wide range of data science applications, including recommender systems, movie references, topic models, medical records, and genomics. In this talk, we introduce the mathematics of low rank models,
demonstrate a few surprising applications of low rank models in data science, and present a simple mathematical explanation for their efficacy.

Evolution of Machine Learning for NIF Optics Inspection | Laura Kegelmeyer | WiDS 2019

Thumbnail for Evolution of Machine Learning for NIF Optics Inspection | Laura Kegelmeyer | WiDS 2019

The National Ignition Facility (NIF) is the most energetic laser in the world. By focusing NIF’s laser beams onto a variety of targets and creating extreme temperature and pressure, scientists from around the world conduct experiments supporting many scientific disciplines including astrophysics, materials science, nuclear science, and using fusion as a clean, safe energy source.

In the course of these experiments, the NIF routinely operates above the damage threshold for its optics. To extend the life of the highly specialized optics, we developed a recycle loop during which each damage site on an optic is identified, measured, tracked through time, protected when it approaches an optic-specific size limit, and then repaired so the optic can be reused.

Here we describe an overview of custom image analysis, machine learning, and deep learning methods used throughout the recycle loop for optics inspection on the NIF beamlines and off. Most recently, we helped automate the optic repair process by identifying microscopic damage before its repair and then evaluating the repaired site for quality control. Since 2007 we’ve used machine learning to improve accuracy and automate tedious processes to enable and inform an efficient optics recycle loop.

This work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under Contract DE-AC52-07NA27344. LLNL-CONF-749953

In the US criminal justice system, jurors choose between two competing hypothesis: the suspect is the source of the evidence found at the crime scene or s/he is not. The likelihood ratio framework, which relies on Bayes’ theorem for assessing the probative value of evidence, is difficult to implement in practice, when evidence is in the form of an image. Machine learning provides a good alternative for determining whether the evidence supports the proposition that the suspect may have been its source. We illustrate these ideas using information about the surface topography of bullet lands.

WiDS Datathon mixes up data science with collaborative teams

If only a data set and some pre-packaged data-analytics software were all it takes to solve real-world problems. The reality is that tools require hands to ply them. And just like a comprehensive data set is better than a limited one, a comprehensive set of skills helps people design better solutions.

Looking at the problem from different perspectives and collaboration are the keys to be able to be successful in data science,” said Srujana Kaddevarmuth (pictured), data science and analytics executive at Accenture LLP and ambassador for the Women in Machine Learning & Data Science team in Bengaluru (formerly Bangalore).

Take a problem like deforestation from palm-oil plantations. Consider all the factors that might be involved: agriculture, climate, ecology, economics, politics, etc. What are the odds that one random data expert can ask all the right questions, pull together all the necessary data, and derive actionable insight? Probably not great.

This is the thinking behind collaborative data-science projects, like the Women in Data Science, or WiDS, Datathon. This year, it organized several teams to collaborate and use data and satellite imagery to analyze this particular problem.

Kaddevarmuth spoke with Lisa Martin (@LisaMartinTV), host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Stanford Women in Data Science event in Stanford, California. They discussed this year’s Datathon and why collaboration results in better outcomes for data scientists.

From clueless to Kaggle code in three weeks
At the WiDS Bengaluru regional event, organizers set up a community workshop. The goal was to form teams to participate in the Datathon. They would submit the fruits of their endeavors to something called Kaggle, a platform for data-science projects and competitions. In India, Kaggle participation is very male heavydespite that region having amazing female data scientists who are innovators in their space with multiple patents, publications and innovations to their credit,” Kaddevarmuth said.

WiDS teamed mentors with participating teams to work together for three weeks. One team from the engineering division who was brand new to Kaggle learned new concepts, honed skills in deep learning and neural networks, and submitted original code to the Kaggle leaderboard.

They were not the top-scoring team, but this entire experience of being able to collaborate, look at the problem from different perspectives, and be able to submit the code despite a lot of these challenges — and also navigate the platform in itself — was a decent achievement from my perspective,” Kaddevarmuth concluded.

Data and company: Intuit’s recipe for successful customer obsession

Many vendors are talking the customer-first talk lately. But who’s walking the walk? What does it take to win customers’ loyalty among so many digitally armed competitors?

The recipe combines technological and human ingredients, according to Kavita Sangwan (pictured), director of technical programs, artificial intelligence and machine learning, at Intuit Inc. For example, Intuit uses customer data to build products with AI and machine learning. This requires the business and financial software company to build trust with its customers.

Intuit operates with the principal and the mindset that this is our customers’ data and we are their stewards,” Sangwan said.So we make sure that we are one of the best stewards for their data.”

Their customers will be able to tell as soon as they use the resulting products. The result is a loop that reinforces Intuit’s bonds with its customers.That’s what we reflect in our products — how we serve them, build intelligent products for them. And that’s how we start to gain trust from our customers,” she added.

Sangwan spoke with Lisa Martin (@LisaMartinTV), host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Stanford Women in Data Science event in Stanford, California. They discussed Intuit’s technological and cultural methods for staying in touch with its customer base.

Pouring more than tech in the product pot
Intuit goes further than gathering data points from customers. It strives to maintain a team of product developers and others that understand customers on a human level. This is how they are able to deliver products they want and need.

It’s very important for us to build a culture which reflects the values and the talents and the skills of our customers,” Sangwan said.

The company strives to put together a team with diverse skills to build smart products that are easy for end users to adopt.It’s very important for us to operate in a team setting,” she stated.A data scientist has to interact with a product manager, a data engineer, a business person, a legal person.”

The diverse skills and knowledge these team members bring are necessary to build its products, Sangwan concluded.

This professor is cleaning up tech’s ‘messy data’ problem

Strong data sets are table stakes for any organization today. Data insights can provide the tentpoles for building a strategic roadmap and offer unexpected learnings for businesses to leverage as new market opportunities. But even the most valuable data set can prove worthless if its insights are entangled in the unstructured digital void.

An estimated 80 percent of all data is unstructured, which renders the intel buried in its complex documents and media files inaccessible without an alternative method of analysis. As information floods the tech industry faster than new talent is prepared to make sense of it, the unstructured data challenge is posing a formidable hurdle for businesses in the digital age.

Madeleine Udell (pictured), assistant professor of operations research and information engineering at Cornell University, is educating a new era of technologists to decode this so-calledmessy data” with a more effective approach to tech collaboration.

Oftentimes people only learn about big, messy data when they go to industry,” Udell said.I’m interested in understanding low dimensional structure in large, messy data sets [to] figure out ways of … making them seem cleaner, smaller and easier to work with.”

Udell spoke with Lisa Martin, host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the recent Stanford Women in Data Science event at Stanford University.

This week, theCUBE spotlights Madeleine Udell in its Women in Tech feature.

The unstructured data challenge
The rise of messy data can be attributed in large part to the influx of information from a growing number of digital endpoints. Internet of things devices deliver a stream ofmessy” data, but the clutter can also come from images, videos, social media, emails, and other data sets not already formatted for simple analysis.

Though more complex and tedious to decipher, these data sources are some of the most highly valued in a market focused on individual user targeting. That gap between ability and potential innovation is what drives Udell’s interest in unstructured data, an area of technology the assistant professor says people entering the tech industry are not adequately prepared for. In her own classes, Udell teaches optimization for machine learning from a messy data perspective.

[The class] introduces undergraduates to what messy data sets look like, which they often don’t see in their undergraduate curriculum, and ways to wrangle them into forms they could use with other tools they have learned as undergraduates,” she said.

Udell’s interest in messy data was piqued when she met the challenge head on working in the Obama 2012 presidential campaign. She was tasked with analyzing voter information but found the unstructured data sets too cumbersome to yield valuable insight.

They had hundreds of millions of rows, one for every voter in the United States, and tens of thousands of columns about things that we knew about those voters,” Udell said.Gender … education level, approximate income, whether or not they had voted in the last elections, and much of the data was missing. How do you even visualize this kind of data set?”

When Udell returned to work on her Ph.D., she was intent on discovering a more efficient method for parsing out value from unstructured data sets.I wanted to figure out the right way of approaching this, because a lot of people will just sort of hack it,” she saidI wanted to understand what’s really going on.”

Making an impact with communication
Udell is as interested in the technical architectures that enable data analysis as she is in supporting organizations through the implementation processes that will allow them to benefit from her work. A comprehensive answer to data management requires both math and communication, and Udell says her broad skill set is part of what has enabled her to make sense of messy data.

If you want your technical work to have an impact, you need to be able to communicate it to other people,” Udell stated.

The social aspect of her role is crucial to finding solutions that actually address user problems and work within existing processes.You need to make … sure you’re working on the right problems, which means talking with people to figure out what the right problems are,” she said.This is … fundamental to my career, talking to people about problems they’re facing that they don’t know how to solve.”

Q&A: Wells Fargo aims for 100-percent data transparency in new era of consumer trust

The big data explosion has created transformative innovation opportunities for technology, as well as businesses across industries. As consumers better understand their piece in that data puzzle and the market begins to find its footing in a data-driven digital landscape, companies must adopt a responsibility around transparency to maintain trust and efficiency.

Greater visibility around data-driven processes can also lead to more comprehensive solutions through interdisciplinary collaboration, according to Kristina Draper (pictured), chief technology officer at Wells Fargo & Co.

Draper spoke with Lisa Martin (@LisaMartinTV), host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Stanford Women in Data Science event in Stanford, California. They discussed the role data is playing in a new era of accountability at Wells Fargo, as well as how Draper is reaching beyond the financial industry for greater innovation opportunities.

[Editor’s note: The following answers have been condensed for clarity.]

Tell a little about your involvement in WiDS, as well as Wells Fargo’s involvement as a sponsor.

Draper: We believe so strongly that in the consumer bank space we have a tremendous opportunity and responsibility to understand how our customers interact with Wells Fargo, and that will require a discipline around data science. We had an opportunity this year to be an executive sponsor and jumped at it. I think we’ll continue to be at that sponsor level in future years.

You were recently named one of the 50 most powerful women in technology. What are some of the [ways] Wells Fargo is re-imagining data and trust? What have you seen of the evolution of females in technology and leadership roles?

Draper: The recognition [of] women in technology … is an opportunity to demonstrate that we should be very confident in the value that we bring as leaders, and that confidence as a woman is hard to come by. I think of my own personal career and the way that doors were opened for me along the way; often we are our own worst enemies. We second guess ourselves, we second guess our value, and we have to really work for that seat at the table.

My coming back to Wells was really … as a leader in technology. I felt I could make a real impact. When I think about what we can do as women leaders in technology and in data science, a lot of it is owning that accountability to leadership and paving the way for leaders behind us. There comes a part in a career, certainly mine, where you’re no longer thinking about the next job for yourself.

We’re in a consumer banking space and financial services, so there’s certainly a lot of places to innovate [and] think about how technology can help to serve a Wells Fargo customer. You need your bank throughout your entire life. Whether you are thinking about a home purchase, an auto purchase, college for your children, retirement, there’s so many big markers in life. And that’s where I get excited about not only the leadership role that I have now, but I have the opportunity to bring a team with me to contribute real value.

You have a pay-it-forward attitude. How are you using that to expand your team … to continue this big re-imagining that Wells Fargo as a business is undergoing?

Draper: WiDS is … a tremendous network opportunity. [I’m] so inspired about how they’re turning data science and really thinking about different problems [and] ways we can improve not only our lives, but the lives of future generations to come.

I come from a financial services background, but the problems that our future generations will face can’t be solved with just one lens. You can’t solve problems with just a financial services expertise or just a technical expertise. It’s the space in between art and science. It’s an ability to think across industry and apply solutions and innovation that have been brought forward through other industries, through other companies, through other academia, and thinking about how that could apply in solving the problems that we’re faced with in the financial services space.

If I turned some of the problems that we’re faced with upside down and thought about it with that perspective, and invited some collaboration to help solve problems, we might come up with a better answer.

How can financial services and the data that you deal with help customers?

Q&A: How AI is cultivating a responsible community to better mankind

Artificial intelligence initiatives powered by big data are propelling businesses beyond the capacity of human labor. While AI tech offers an undeniable opportunity for innovation, it has also sparked a debate around potential misuse through the vast reach of programmed biases and other problematic behaviors.

The power of AI can be comprehensively harnessed for good by fostering diverse teams focused on ethical solutions and working in tandem with policymakers to ensure responsible scale, according to Janet George (pictured), fellow and chief data officer at WD, a Western Digital Company.

George spoke with Lisa Martin (@LisaMartinTV), host of theCUBE, SiliconANGLE Media’s mobile livestreaming studio, during the Stanford Women in Data Science event in Stanford, California. They discussed the range of possibilities in AI and how WD is leveraging the technology toward sustainability.

[Editor’s note: The following answers have been condensed for clarity.]

Tell us about Western Digital’s continued sponsorship and what makes this important to you.

George: Western Digital has recently transformed itself … and we are a data-driven … data-infrastructure company. This momentum of AI is a foundational shift in the way we do business. Businesses are realizing that they’re going to be in two categories, the ‘have’ and the ‘have not.’ In order to be in the have category, you have to embrace AI … data … [and] scale. You have to transform yourself to put yourself in a competitive position. That’s why Western Digital is here.

How has Western Digital transformed to harness AI for good?

George: We are not just a company that focuses on business for AI. One of the initiatives we are doing is AI for Good and … Data for Good … working with the UN. We’ve been focusing on trying to figure out the data that impacts climate change. Collecting data and providing infrastructure to stow massive amounts of species data in the environment that we’ve never actually collected before. Climate change is a huge area for us, education … [and] diversity. We’re using all of these areas as a launching pad for Data for Good and trying to use data … and AI to better mankind.

Now we have the data to put out massively predictive models that can help us understand what the change would look like 25 years from now and take corrective action. We know carbon emissions are causing very significant damage to our environment and there’s something we can do about it. Data is helping us do that. We have the infrastructure, economies of scale. We can build massive platforms that can stow this data and then we can analyze this data at scale. We have enough technology now to adapt to our ecosystem … and be better in the next 10 years.

What are your thoughts on data scientists taking something like a Hippocratic Oath to start owning accountability for the data that they’re working with?

George: We need a diversity of data scientists to have multiple models that are completely diverse, and we have to be very responsible when we start to create. Creators have to be responsible for their creation. Where we get into tricky areas are when you are the human creator of an AI model, and now the AI model has self-created because it has self-learned. Who owns the copyright to those when AI becomes the creator? The group of people that are responsible for creating the environment, creating the models, the question comes into how do we protect the authors, the users, the producers, and the new creators of the original piece of art.

You can use the creation for good or bad. The creation recreates itself, like AI learning, on its own with massive amounts of data after an original data scientist has created the model. Laws have to change; policies have to change. Innovation has to go, and at the same time, we have to be responsible about what we innovate.

Where are we as a society in starting to understand the different principles and practices that have to be implemented in order for proper management of data to enable innovation?

George: We’re debating the issues. We’re coming together as a community. We’re having discussions with experts. What are we seeing as the longevity of that AI model in a business setting, in a non-business setting? How does the AI perform? We are now able to see the sustained performance of the AI model.

Bhavani Thuraisingham, Professor of Computer Science at University of Texas at Dallas, presents Integrating Data Science and Cyber Security at the WiDS 2018 Conference held at Stanford University on March 5, 2018.

The collection, storage, manipulation, analysis and retention of massive amounts of data have resulted in serious security and privacy considerations. Various regulations are being proposed to handle big data so that the privacy of the individuals is not violated. For example, even if personally identifiable information is removed from the data, when data is combined with other data, an individual can be identified. While collecting massive amounts of data causes security and privacy concerns, big data analytics applications in cyber security is exploding. For example, an organization can outsource activities such as identity management, intrusion detection and malware analysis to the cloud. The question is, how can the developments in data science techniques be used to solve security problems? Furthermore, how can we ensure that such techniques are secure and adapt to adversarial attacks? This presentation will first describe our research in data science including in stream data analytics and novel class detection and discuss its applications to insider threat detection. Second, it will discuss the emerging research area of adversarial machine learning. Finally, it will discuss why women should pursue careers in data science.

Dawn Woodard, Senior Data Science Manager of Maps at Uber presents Dynamic Pricing and Matching in Ride-Sharing at the WiDS 2018 Conference held at Stanford University on March 5, 2018.

Ride-sharing platforms like Uber, Lyft, Didi Chuxing, and Ola are transforming urban mobility by connecting riders with drivers via the sharing economy. These platforms have achieved explosive growth, in part by dramatically improving the efficiency of matching, and by calibrating the balance of supply and demand through dynamic pricing. The dynamic adjustment of prices ensures a reliable service for riders, and incentivizes drivers to provide rides at peak times and locations. Dynamic pricing is particularly important for ride-sharing, because pricing too low causes pickup ETAs to get very long, which reduces the efficiency of the platform and causes a poor experience for riders and drivers. We review the literature on matching and pricing techniques in ride-sharing. We also discuss how to estimate several key inputs to those algorithms: predictions of demand, supply, and travel time in the road network.

The upstream oil & gas industry (i.e. the exploration for and production of hydrocarbons) needs to reap the benefits of new technology to improve efficiency. Making more effective use of increasing amounts of collected data is on the verge of transforming the business.

Transformation through data analytics is equally relevant on both the operational and financial sides of the business.
On the upstream operational side: for decades now, we have been inventing new and increasingly sophisticated tools (both hardware and software) to generate new data types that extend the boundaries of geoscience knowledge, and allow us to understand our hydrocarbon reservoirs in ever increasing detail. Historically, we have processed only a fraction of the data collected, but that is changing. Now, among the most important criteria governing the efficiency of oil and gas companies are the hugely increased volume of data collected but also the variety, velocity and veracity of information that can be extracted from that data. That’s data science! Data analytics as a discipline is now increasingly integrated within our upstream workflows in drilling, reservoir characterization and the actual production (extraction) of hydrocarbons in the most economically efficient ways possible. To this end, one goal is the development of an analytics platform that will perform a key role in increasing productivity through the simultaneous optimization of drilling planning and execution, the improvement of asset utilization and the overall reduction of non-productive time.

On the financial side: the oil and gas industry has a long history of being secretive and, as a result, judgment of the quality and accuracy of non-technical data has proved very difficult. In general, insufficient attention has been paid to addressing these challenges leading to unnecessary volatility in price movements through inadequate or conflicting data, and this volatility impacts decision-making within companies. In the information age, where markets react instantaneously to a multitude of data sources, it is time to understand better this key driver of our industry. Decision-enabling information is extremely critical to the efficient functioning of an industry that is driven by the signals coming from commercial markets. Understanding the quality and accuracy of that information through data science is a key enabler in filling a major gap currently preventing more effective management of oil and gas company assets.

Digital transformation, implying the transition from desktop to the cloud and mobile devices, easy access to information, new scalable online services and automated industrial workflows, is about to radically change the way we work in any industry (oil and gas, defense, transport, automotive, medicine, telecom, logistics, etc). This is no longer a trend, but a reality clearly demonstrated by the world’s most valuable companies adopting expanded and enhanced data analytics in response to common drivers of operational efficiency, operational safety and accuracy of real-time decision-making. That’s the promise of Big Data, to really understand the systems that make our technological industry. As you begin to understand the interactions of all the constituent components then you can build systems that are better and more effective at addressing the key industry drivers, irrespective of the industry. New technology is increasingly playing a huge new role. Data is the new oil!

Dr. Gottlib-Zeh describes how data science is transforming the oil and gas industry for better planning and efficiency, for both drilling and production.

Beware what you ask for: The secret life of predictive models | Claudia Perlich | WiDS 2017

Thumbnail for Beware what you ask for: The secret life of predictive models | Claudia Perlich | WiDS 2017

Predictive modeling and its variants are at the core of an increasing number of technical advances that touch us in every aspect of our life. Today, nobody doubts the ability of machines to learn from historical data and predict with far higher accuracy than any human. But real world applications of machine learning are often a far cry from the well understood academic assurances of how these algorithms should behave. In this talk I will share some practical lessons when models had a surprising secret life and did something very different from what I thought I had asked them to do. As the creators of machine learning solutions it is our responsibility to pay attention to the often subtle symptoms and to let our human intuition be the gate keeper deciding when our models are ready to be released ‘into the wild’.

Claudia Perlich, Chief Scientist at Dstillery, talks about how data scientists need to use a combination of data science and intuition to deliver accurate insights from data sets.

Google it: The evolution of search | #WiDSConference
by Marlene Den Bleyker | Nov 13, 2015

https://siliconangle.com/2015/11/13/g…

Google, the trailblazer of all search engines, has made a powerful impact over the years in the way users and businesses interact online.

Carrie Grimes, distinguished engineer at Google, has been with the company since its early days, and she caught up with Jeff Frick, host of theCUBE, from the SiliconANGLE Media team, at the Women in Data Science Conference held at Stanford University to explain Google’s processes and the evolution of search.

The new questions

In the past, to extract meaningful data meant using algorithms; however, Grimes stated, “Now we actually have to ask questions, such as how do you make a business decision based on this data.” She believes that blending the computational ability of computer science with the confidence gained from statistics is critical for companies such as Netflix, Amazon or Google to make business-based decisions.

Grimes describes how traditionally the goal is to look at customer and user data and derive value, but now it is also essential to focus on the backend, where data science is really important to help make business decisions. According to Grimes, some of the considerations are: “How do I use data science to pick the optimal point? How much computational power do I put into indexing a tweet versus the value of going out and getting a whole new set of content that is more static?”

Grimes pointed out that you can’t force the algorithms Google uses to index, to crawl and to find the right meaning of content and keywords. She referenced the amount of content people are creating and having to decide whether to invest in compute power or invest in a feature, a cool new rendering or the ability to understand structured data. ‚ÄúThat’s the kind of tradeoff we have internally,‚Äù she said.

New data issues to tackle

Grimes has worked for Google since 2003 and has seen the steady need to progress and adapt. She commented on how industry outsiders don’t understand the pressure from users. As search becomes more intelligent, customer expectations become higher.

When she began her career at Google, she recalled that a great deal of effort went into content that was static, managing scale and moving data around. Now, personalized recommendations and understanding the nuances about knowing who is searching and what the searches mean are a much larger focus for data scientists today than it was 10 years ago.

Network Science: From the Online World to Cancer Genomics | Jennifer Chayes | WiDS 2015

Thumbnail for Network Science: From the Online World to Cancer Genomics | Jennifer Chayes | WiDS 2015

Everywhere we turn these days, we find that networks can be used to describe relevant interactions. In the high tech world, we see the Internet, the World Wide Web, mobile phone networks, and a variety of online social networks. In economics, we are increasingly experiencing both the positive and negative effects of a global networked economy. In epidemiology, we find disease spreading over our ever-growing social networks, complicated by mutation of the disease agents. In biomedical research, we are beginning to understand the structure of gene regulatory networks, with the prospect of using this understanding to manage many human diseases. In this talk, I look quite generally at some of the models we are using to describe these networks, processes we are studying on the networks, algorithms we have devised for the networks, and finally, methods we are developing to indirectly infer network structure from measured data. I’ll discuss in some detail particular applications to cancer genomics, applying network algorithms to suggest possible drug targets for certain kinds of cancer.

One of the challenges in big data analytics lies in being able to reason collectively about extremely large, heterogeneous, incomplete, and noisy interlinked data. We need data science techniques that can represent and reason effectively with this form of rich and multi-relational graph data. In this talk, I will describe some common inference patterns needed for graph data including: collective classification (predicting missing labels for nodes), link prediction (predicting potential edges), and entity resolution (determining when two nodes refer to the same underlying entity). I will describe some key capabilities required to solve these problems, and finally I will describe a highly scalable open-source probabilistic programming language being developed within my group to solve these challenges.
