2020 Projects

 

The American Communities Computable Newspaper Database
Melissa Dell (Harvard Faculty of Arts and Sciences)

The American Communities Computable Newspaper Database uses recent advances in deep learning, computer vision, and natural language processing to create a computable database for over 7,000 historical newspapers in all 50 states, across over 12 million newspaper editions. The database will provide straightforward-to-use outputs from natural language processing analyses conducted on full article texts, image captions, and headlines, that can be used to elucidate how the media has influenced American society.

Discovery of higher temperature superconductors by machine-learning strongly correlated descriptors of materials
Xin Li (Harvard John A. Paulson School of Engineering and Applied Sciences)

Project Website
The project aims to make a search and design of higher temperature superconductors by a combination high-throughput ab initio simulations and machine learning analyses that focuses on novel descriptors of ultrafast electron dynamics. The project may also lead to an understanding of the unconventional superconducting mechanism.

Refining pre-disaster strategic preparedness: A machine learning model for identification of communities facing the highest health risks from an impending tropical cyclone.
Rachel Nethery (Harvard T.H. Chan School of Public Health)

Climate change is expected to increase the intensity of tropical cyclones (TC), thus they represent an escalating risk to human health over this century. Motivated by our large database of historic TC exposures and Medicare health records, we will create a predictive machine learning tool that provides information in real-time about the areas of highest health risk and the types of health risks anticipated for an impending TC threatening the United States, with the goal of maximizing the protective impact of strategic preparedness efforts.

A theory of how deep networks generalize beyond their training set
Cengiz Pehlevan (Harvard John A. Paulson School of Engineering and Applied Sciences)

Deep networks are extremely successful in finding statistical patterns in data that generalize to previously unseen samples, yet how they can do so remains an open question. We will develop a theory of generalization in deep networks adopting mathematical methods from the statistical physics of disordered systems.

Planning proposal to establish a Harvard Initiative in Functional Neuroscience (HIFUN)
Adam Cohen (Harvard Faculty of Arts and Sciences)​​​​​​​

Scalable algorithms for Bayesian inference with multiple sources of streaming data
Pierre Jacob (Harvard Faculty of Arts and Sciences)​​​​​​​

In various domains, data sets take the form of collections of time series, which calls for specific methodological research in data science. In this project, we consider various statistical questions arising with two types of data sets: one contains recordings of the activity of multiple neuronal units in the brain of mice during experiments, and the other contains partial genetic measurements collected on large populations of malaria parasites. In the first case, the project considers how to cluster time series in meaningful groups; in the second case how long should each time series be in order to obtain the desired estimation accuracy.

Smartphone-based Digital Phenotyping of Structure and Content of Communication
JP Onnela (Harvard T.H. Chan School of Public Health)

Smartphone-based digital phenotyping makes use of active data (e.g., surveys) and passive data (e.g., location data, activity data, communication data) to learn about social, behavioral, and cognitive phenotypes in free-living or naturalistic settings. In this project, we will develop new statistical methods methods for quantifying longitudinal changes in the social structure of communication networks in individuals with central nervous system disorder.​​​​​​​

New frontiers in statistical modeling and data science for uncertainty quantification in climate science
Natesh Pillai  (Harvard Faculty of Arts and Sciences)​​​​​​​

Accurate quantication of the long-term changes in temperature and careful analysis of the resulting implications constitute one of the pressing problems of our times. Long, high-quality records of temperature provide an important basis for our understanding of climate variability and change. However, even a perfunctory glance at most of the available temperature records will indicate a huge amount of uncertainty from various sources including measurement error, preprocessing of the data before it is made publicly available, etc. Thus to meaningfully contribute to the global warming debate, it is imperative that we provide a scientically rigorous uncertainty quantication of the temperature, incorporating careful statistical modeling, domain knowledge and technical expertise for handling large, complex data. This proposal is a call-to-arms to address this urgent issue.

 

2017 Projects

 

Learning from Noisy and Strategically-Generated Data
Yiling Chen (Harvard John A. Paulson School of Engineering and Applied Sciences)​​​​​​​

Improving Health Care System Performance: Computational Health Economics with Normative Data for Payment Calibration
Sherri Rose (Harvard Medical School)​​​​​​​

In the conventional framework for designing health plan payment models, the regulator chooses variables to be used as risk adjustors, the risk adjustment weights, and other policy parameters, but the data from which estimates are derived are taken as given. This implicitly assumes the observed spending patterns are optimal, despite our knowledge that they are not. The work funded by this Harvard DSI grant, published in the Journal of Health Economics, developed new data transformation methods for the preprocessing phase to address this issue and induce a fairer and more efficient health care system.

Inference, Design of experiments, and Experimentation in an Automated Loop (IDEAL) for Aging Research
Jeffrey Miller (Harvard T.H. Chan School of Public Health)

Optimizing Sepsis Management with Reinforcement Learning
Finale Doshi-Velez (Harvard John A. Paulson School of Engineering and Applied Sciences)​​​​​​​

Off-policy evaluation considers the task of estimating the value of some proposed treatment policy given data collected from some behavior policy (e.g. estimating how well an alternate treatment strategy may perform given data from doctors treating patients using current approaches). The main outcomes of this grant were (a) to describe a set of common pitfalls for when off-policy evaluation may fail in real settings, and provide guidelines to identify when those may be happening, and (b) to develop novel approaches for improved off-policy evaluation.

Deep Learning in Particle Physics
Matthew Schwartz  (Harvard Faculty of Arts and Sciences)​​​​​​​

This award supported research on applying modern machine learning techniques to the analysis of collider data in particle physics. Techniques were developed for signal and background discrimination, data purification, and interpretable data-driven weakly-supervised and unsupervised learning.
