Title: Multiscale inverse problem, from Schroedinger to Newton to Boltzmann
Speaker: Qin Li, Department of Mathematics
Date + Location: 7 March (Monday), Orchard View Room
Abstract: Inverse problems are ubiquitous. People probe the media with sources and measure the outputs. At the scale of quantum, classical, statistical and fluid, these are inverse Schroedinger, inverse Newton’s second law, inverse Boltzmann problem, and inverse diffusion respectively. The universe, however, should have a universal mathematical description, as Hilbert proposed in 1900. In this talk, we present a line of research results that unify all these inverse problems. Facing the IFDS crowd, I’d like to ask the following question: how to integrate the mathematical equivalence into the optimization formulation for a more efficient algorithmic pipeline than the traditional PDE-constrained optimization?
Bio: Qin Li is an associate professor of mathematics at UW-Madison. Her research lies between scientific computing and PDE-constrained optimization.

Title: Constrained text generation through discrete and continuous inference
Abstract: Neural text generation has shifted to generating text with large-scale, general-purpose models coupled with generic inference algorithms. An important open question is how to efficiently offer control over generated text. We describe two algorithms for enabling control through inference-time constraints: (i) A*-Neurologic, a discrete search algorithm for incorporating logical constraints through estimates of the future, and (ii) COLD decoding, which treats generation as continuous gradient-based sampling from an energy function that captures task-relevant constraints. Our algorithms can be applied directly to off-the-shelf models without the need for task-specific finetuning, and result in strong performance on a variety of generation tasks.

IFDS Ideas Forum: A Review of Neural Collapse
2022-03-28 12:30 - 13:30 (America/Chicago) | Orchard View Room, 330 N. Orchard Street, 3rd Floor NE, Madison, Wisconsin, 53715, United States
Speaker: Greg Canal
Abstract: Neural Collapse is a recently discovered phenomenon in deep neural network training that describes class separation in the final network layers. When a classification network is trained past the point of zero training error, it has been observed that the penultimate layer activations collapse to their respective class means, the means themselves form a simplex equiangular tight frame, and the final layer linear classifiers align with each respective mean. Neural collapse has been demonstrated both empirically on deep networks as well as theoretically on simplified models, and has inspired new questions on generalization, robustness, and architecture design. In this talk I will review the original discovery of neural collapse, as well as recent literature that expands on related questions.
