Title: Learning from Weak SupervisionAbstract: Deep learning models often rely on high-quality labeled data, yet such resources are scarce and costly in domains like public health and healthcare. This dissertation addresses the problem of learning from weak supervision, where labels are noisy, incomplete, or coarse. This dissertation focuses on two major regimes: noisy supervision, which involves developing strategies to learn effectively from mixed- and unknown-quality labels, and indirect supervision, which entails designing methods that leverage coarse-grained signals to guide fine-grained tasks, such as rationale extraction and clinical notes summarization. Across four tasks, novel approaches are proposed to reduce dependence on expert annotations, mitigate label noise and imbalance, and exploit existing high-level signals. This work contributes to the development of robust, scalable models that enhance clinical decision support and medical text understanding.

Ludwig Boltzmann was unsatisfied with fluid theory (Navier-Stokes Eq., etc.) as it lacked a microscopic theory that could explain the irreversibility at the core of thermodynamics. He committed himself to show how the disbelieved notion of atoms could unravel fluid dynamics into a stochastic particle theory. This talk is about my research program to similarly find a microscopic and ballistic theory of “particles” that generates quantum mechanics, while staying within the guard rails of Einstein’s notion of “realism”. We will visit several less traveled areas of quantum theory and mathematics while following a path to this goal and end with a demonstration of a computational demonstration.David Cyganski Professor Emeritus, Electrical and Computer Engineering, RBE - WPIAll Faculty and students are welcome and encouraged to join us!

Quasi-independence models are log-linear models that describe a situation in which some states of X and Y cannot occur together, but X and Y are otherwise independent. We characterize which quasi-independence models have rational maximum likelihood estimator, or MLE, based on combinatorial features of the bipartite graph associated to the model. In this case, we give an explicit formula for the maximum likelihood estimate. We also give a substantial introduction to algebraic statistics, which will be accessible to advanced undergraduate students.
