Reweighted Information Inequalities

Speaker: Jonathan Niles-Weed, Courant Institute, New York University

Location: Warren Weaver Hall 1302

Date: Friday, April 24, 2026, 1 p.m.

Synopsis:

This talk will give an introduction to the analysis of overdamped Langevin dynamics via functional inequalities (log-Sobolev and transportation-information inequalities) and discuss a new class of such inequalities for mixtures. These "reweighted" information inequalities offer user-friendly explanations of phenomena that appear in non-log-concave sampling.
