Question Asking with Differing Knowledge and Goals
Research Assistant: Kesong Cao

Photo of Joe AusterweillPeople spend a significant proportion of their time asking each other questions to gather information. Entire professions, such as academia and customer service, are dedicated to asking and answering questions. Despite tremendous progress in machine learning, automated methods that answer a person’s questions are still inferior to answers from people.

Why are people better at answering questions? One reason is that question-askers leave out information that those answering the questions can fill in from their rich knowledge of language and the world. A recent machine learning method addresses this issue by asking multiple, reformulated versions of a human question, providing multiple answers, and learning to select the answer that is most likely to satisfy a person. However, this is done purely from data and does not incorporate psycholinguistic research demonstrating that people prefer simpler answers that are tailored to their personal goals and knowledge.

This project investigates whether incorporating psycholinguistic factors can improve automated question-answering methods. If so, then researchers can test novel, potential psycholinguistic factors and learn more about the underlying mechanisms that enable people to answer questions.

Machine Learning Approaches for Metadata Standardization
Co-PI: Mark Craven; Scientist: Yuriy Sverchkov; Research Assistant: Tapanmitra Ravi

Photo of Colin DeweyResearchers and businesses are increasingly using large data sets, compiled from many sources, for training machine learning systems and performing statistical analyses. A major bottleneck arises from the fact that compiled data sets often contain unstandardized, unstructured metadata that describe each record. Manual standardization of metadata is labor intensive and often requires substantial expertise in the field of study.

To mitigate this issue, this project will develop machine learning approaches for automating the task of metadata standardization in large, heterogeneous data sets. The researchers will use state-of-the-art natural language processing models and develop active learning algorithms, which facilitate identification of records that would most benefit from human expert input. They will demonstrate the performance of these methods on the Sequence Read Archive—a vast repository of public biological sequence data.

Using Data to Foster Entrepreneurship and Innovation in the Madison Ecosystem
Research Assistant: Bekhzod Khoshimov

Entrepreneurship is an important path for upward mobility and wealth creation. Student entrepreneurship matters, in part, because student startups are not necessarily modest endeavors. In 1979, recent UW-Madison graduate Judy Faulkner founded the electronic medical records company Epic, which today employs over 10,000 people. Research indicates that student-entrepreneurship at UW-Madison is surprisingly prevalent.
Despite the impact of student entrepreneurship, little is known about what drives entrepreneurial intentions and activity amongst students, such as an interest in starting a company. Further, female students are less than half as likely as male students to self-report entrepreneurial intentions or actions.

The goal of this project is to support the work of the Academic Entrepreneurship Study Team at UW-Madison. This team is using data analysis techniques to enhance the impact and management of entrepreneurship programs at UW-Madison and other U.S. universities. Insights from this research will support the creation of evidence-based interventions to increase the prevalence and effectiveness of student entrepreneurship.

Fairness Guarantees for Learners Without Explicit Access to Demographics

The most advanced sample complexity bounds on fair machine learning are called multicalibration convergence bounds. These bounds specify the number of samples required to achieve performance parity across many population demographics. This project will yield additional perspective on both algorithmic fairness and multicalibration error convergence bounds. Further, it will enable machine learning practitioners to easily understand the convergence behavior of multicalibration error for a myriad of classifier architectures.

Adaptive Operations Research and Data Modeling for Insurance Applications
Research Assistant: Cheng-Wei Lu

Photo of Michael FerrisUncertainty abounds in decision problems and optimization is a key tool used to mitigate its effects, utilizing the power of data science. This project will deploy a new approach that separates strategic decision making from operational modeling, in the context of a claim adjustment problem in the insurance industry. In this setting, random accidents occur across a large service area, requiring agents to deploy to the site to assess, document and determine appropriate courses of action. Our approach differentiates normal workload from crisis situations. It will inform an operational model that schedules resources over time to service both routine, normal workloads in a cost-effective manner, and enable the company to react efficiently to crisis situations. The model can be applied to problems as diverse as disaster recovery, chemical spill mitigation and electricity planning for extreme weather events.

A Deep Learning Approach to User Location Privacy Protection
Co-PI: Jerry Zhu

Picture of Song GaoUser location information is a key component of both research and business intelligence. With the increasing availability of mobile devices and popularity of mobile apps, users in social network platforms actively share rich information about their locations on the Earth, the places they go and the activities they engage in. Those location-based profiles provide an invaluable source of information. However, mobility data is among the most sensitive data being collected by mobile apps, and users increasingly raise privacy concerns. The proposed research aims to develop a deep learning architecture that will protect users’ location privacy while keeping the capability for location-based business recommendations. The algorithms developed through this research may be applied in usage-based insurance (UBI) and other location intelligence domains.

Counterfactual Evaluation of Sequential Decision Policies

One way to evaluate AI-based decision-making policies and autonomous systems before they are deployed is to take data from a previously used policy and answer the counterfactual question, “What would have happened if the new policy had been making decisions instead of the older policy?” This project will introduce novel methods for counterfactual policy evaluation in sequential decision-making, where even small changes in how decisions are made can lead to drastically different outcomes over time.

Auto-labeling Foundations
Co-PI: Fred Sala

While crowdsourcing is a popular way to collect labeled training data for machine learning, it is expensive and time-consuming to hand-label each data point. Systems that automatically label data points while actively learning a model perform well in practice, but there is no theoretical understanding of what performance guarantees can be expected from these systems, or whether the resulting biased datasets can even be trusted. This project aims to close this gap by developing theoretical foundations for characterizing the performance of auto-labeling systems.

Query Design for Crowdsourced Clustering: Efficiency vs. Noise Trade-off

While crowdsourcing is a popular way to collect labeled training data for supervised machine learning, non-expert crowdworkers often provide noisy answers. This project aims to increase understanding of how the ability of humans to learn and retain new concepts affects the quality and cost of crowdsourced data.

GAN-mixup: A New Approach to Improve Generalization in Machine Learning
Co-PI: Dimitris Papailiopoulos

Photo of Kangwook LeeThe recent successes of machine learning hinge on the ability of predictive models to generalize, or adapt well to previously unseen data. Data augmentation, the process of injecting artificial data points into a training set, is widely employed for improving generalization. One of the most prominent data augmentation algorithms is mixup, which helps achieve state-of-the-art generalization performance across several benchmark tasks.

While mixup algorithms are useful for improving generalization for a wide class
of tasks, they have a few critical limitations. Mixup sometimes degrades generalization, restricting the applicability of these tasks. Moreover, current mixup algorithms do not have any theoretical performance guarantees. To address these challenges, the researchers will develop a computationally efficient mixup algorithm based on a generative adversarial network (GAN). They will also develop a theoretical framework for analyzing the performance of various mixup algorithms. This research will provide a new approach to improve generalization, with provable performance guarantees.

Integer Programming for Mixture Matrix Completion
Co-PIs: Jim Luedtke and Daniel Pimentel-Alarcon; Research Assistant: Akhilesh Soni

Photo of Jeff LinderothMatrix completion, or filling in the unknown entities in a matrix, is one of the most fundamental problems in data science. Matrix completion is used in applications such as recommender systems that predict the rating a user would give to an item, such as a movie or product, and then make recommendations to the user. This project will develop algorithms for solving a mixture matrix completion problem (MMCP), which has important applications not only in recommender systems, but also in computer vision systems for processing and analyzing visual images, data inference, and outlier detection.

Key to this research will be the development and application of advanced algorithmic techniques from integer programming, a powerful mathematical tool for solving optimization problems involving discrete choices. The work will pave the way towards the application of integer programming for a broad class of large-scale data science problems.

Knowledge graphs encode human expertise in a structured manner to enhance the performance of recommender, forecasting, and other machine learning systems. As new concepts emerge in a domain, knowledge graphs need to be expanded to include them. However, expanding knowledge graphs manually is infeasible at scale. In this work, we propose methods to automatically expand knowledge graphs that are designed from the ground up to operate with humans in the loop.

Optimizing Question and Answer Systems via User Feedback
Research Assistant: Subhojyoti Mukherjee

Question-and-Answer (Q&A) systems are online software systems that aim to answer questions asked by users. Such systems are increasingly common throughout business, industry and healthcare. This project aims to develop new theory and methods for optimizing Q&A systems based on user feedback.

This project will begin with text embeddings that map words, sentences and whole documents into numerical representations that find similarities and connections in language. The research will draw on recent advances in the field of multi-armed bandit problems—a modeling approach that balances the choice of acquiring new knowledge with the competing choice of relying only on existing knowledge—to explore new approaches for Q&A systems. The research team will develop scalable algorithms for these systems with attention to search optimization and computation time, as human users of Q&A systems will not tolerate large delays in receiving answers to questions.

Improving Traffic Safety Outcomes Through Data Science

While advances during the last 40 years in vehicle design, traffic engineering and driver behavior have led to significant improvements in transportation safety, recent trends have shown a leveling—and in some cases an increase—in the number of traffic crash fatalities. Emerging data provide new opportunities for incentives and technologies that move the trend towards zero fatalities once again. However, there are vital research questions about which technologies hold the most promise and how these different solutions work together to help drivers make informed, safe decisions.

The vision for this research is to translate advances in automotive technology and data science into tools that will improve driver safety and bolster the safety performance of emerging technologies, such as advanced driver assistance systems and automated vehicles. The researchers will conduct collaborative data science research, including machine learning and other approaches, to develop algorithms focused on incentivizing positive driver behavior. Researchers will also quantify the safety performance of emerging technologies, filling information gaps for automated vehicle developers, insurance companies, policy makers and the public.

Learning Causal Relationships from Data
Co-PI: Aubrey Barnard; Research Assistant: Ryan Kassab

Photo of Irene OngHumans naturally develop an understanding of cause and effect by exploring the world. But causality is not nearly so easy for machines to learn. As a result, causal understanding is often missing from artificially intelligent systems, as you may have noticed when your digital assistant goes awry. To help improve the causal reasoning abilities of such systems, this research project develops an algorithm for learning causal relationships from data, one that is more efficient, accurate and robust than similar algorithms. These characteristics make causal learning more usable and likely to be incorporated into systems like your digital assistant in the future.

For the time being, the causal learning algorithm will be applied to discovering the environmental factors that prevent or cause asthma, and to identify relationships in electronic health data that will help prevent severe drug reactions and improve patient care by tailoring it to each individual patient.

Developing Novel Mixed Reality Tools for Consumer Insurance Documentation
Co-PI: Ross Tredinnick

Documentation and assessment of personal property following accidents or disasters is a major component of the insurance claims process. This project will take advantage of recent technological advances to create mixed reality 3D models and develop an application that allows for a more thorough inspection of damages.

3D Capture and Scanning Technology for Insurance Documentation

Insurance claims adjusters constantly face the challenge of inspecting and assessing a scene to understand potential risk, or what took place after an event. They typically do this using tools such as digital photography. Recent advances in 3D capture technologies have created new ways to digitize the world around us. The overall goal of this project is to design and implement a system that utilizes 3D scanning and capture technology for automated documentation of scenes. This has the potential to reduce disputes between insurance companies and their clients, saving money and time for both parties.

Kevin Ponto portraitAs the utilization of 3D capture technology in this area is quite novel, and upcoming technological changes may create new directions of inquiry, the project will focus on research and design of an automated inventory system. This work will provide foundational knowledge for how 3D capture technologies may benefit the insurance industry.

Data-Aware Model Recycling
Co-PI: Dimitris Papailiopoulos; Research Assistants: Saurabh Agarwal and Tsu-Tao Chang

Model Recycling: Accelerating Machine Learning by Re-using Past Computations
Co-PI: Dimitris Papailiopoulos

Data scientists train machine learning models that are used in a wide range of domains, from drug discovery to recommendation engines. Training a machine learning model, and fine-tuning the parameters that control how well a model performs, take significant time and resources. The process of incremental fine-tuning is often manual and involves retraining models from scratch. This project will automate and accelerate this process of fine-tuning by reusing and sharing past computations from prior training jobs, using a technique called model recycling. The researchers will develop a software framework that can help data scientists accelerate model fine-tuning, and a proposed intelligent predictor that can automatically save prior computation results, based on their importance.
