    “Watching your Weights: Generalizing from a Randomized Trial to a ‘Real World’ Target Population”

    Randomized controlled trials are often thought to provide definitive evidence on the magnitude of treatment effects. But because treatment modifiers may have a different distribution in a real world population than among trial participants, trial results may not directly reflect the average treatment effect that would follow real world adoption of a new treatment. Recently, weight-based methods have been repurposed to more provide more relevant average effect estimates for real populations. In this talk, I summarize important analytical choices involving what should and should not be borrowed from other applications of weight-based estimators, make evidence-based recommendations about confidence interval construction, and present conjectures about best choices for other aspects of statistical inference.

    On Representations and Fairness: A Few Information-Theoretic Tools for Machine Learning

    Information theory can shed light on the algorithm-independent limits of learning from data and serve as a design driver for new machine learning algorithms. In this talk, we discuss a set of information-theoretic tools that can be used to (i) help understand fairness and discrimination in machine learning and (ii) characterize data representations learned by complex learning models. On the fairness side, we explore how local perturbations of distributions can help both identify proxy features for discrimination as well as repair models for bias. On the representation learning side, we explore a theoretical tool called principal inertia components (PICs), which enjoy a long history in the statistics and information theory literature. We use the PICs to scale-up a multivariate statistical tool called correspondence analysis (CA) using neural networks, enabling data dependencies to be visualized and interpreted at a large scale. We illustrate these techniques in both synthetic and real-world datasets and discuss future research directions.

    Inclusion and Representation in the Sciences

    164 Angell Street

    This event will showcase three student-driven courses at Amherst, Brown, and Yale that focus on inclusion and representation in the sciences and provide an opportunity to engage in discussions about the content and impact of these courses. The “Being Human in Stem” Initiative at Amherst and Yale aims to foster a more inclusive, supportive STEM community by helping students, faculty, and staff collaboratively develop a framework to understand and navigate diverse identities in the classroom, lab, and beyond. The Brown course on “Race and Gender in the Scientific Community” examines disparities in representation in the scientific community, issues facing different groups in the sciences, and paths towards a more inclusive scientific environment.

    Keynote address takes place in Foxboro Auditorium, Kassar House, 151 Thayer St.

    3rd NorthEast Computational Health Summit (NECHS) 2019

    South Street Landing

    On Friday April 26th, Brown University and IBM Research are co-hosting the 3rd NorthEast Computational Health Summit (NECHS) focused on the latest developments in Personal and Population Health in the Digital Era. The goal of the summit is to foster communication and collaboration among clinicians, medical informaticists, and computational researchers in the northeast.

    The summit will feature two invited keynotes:

    • Susan Murphy, Professor of Statistics, Professor of Computer Science at the Harvard John A. Paulson School of Engineering and Applied Sciences and Radcliffe Alumnae Professor at the Radcliffe Institute, Harvard University
    • Peter Embi, President & CEO Regenstrief Institute; Associate Dean for Informatics & Health Services Research, Indiana University School of Medicine

    There will also be an invited panel presentation led by Benjamin Marlin of the University of Massachusetts, Amherst as well as submitted papers and posters on various aspects of digital health including deep learning, observational studies, predictive modelling, translational informatics, patient engagement and health behavior.

    There will be ample time for less formal interactions during lunch, as well as during the poster session and breaks.
