Austin STROMME – “Statistical optimal transport: barycenters and entropic regularization”

https://zoom.us/j/98407728890?pwd=aEgzaVJvd0xCZEZnTUg5emtIRGJYZz0

Abstract:

Optimal transport (OT) is a popular paradigm for comparing and interpolating datasets using a minimum energy criterion, and gives rise to a Riemannian-like geometry on probability distributions. In this talk, we’ll study statistical and connected algorithmic questions relating to some of the most promising facets of OT: barycenters, OT on Gaussians, entropic regularization, and transfer learning. Throughout, we’ll emphasize dimension-free rates of estimation and practical algorithms, as well as the geometry and optimization-centric viewpoint that yields such results.
