Announcements

We welcome volunteers for presentations! A list of interesting papers is here, where you can indicate interest in presenting a paper, or suggest a paper for someone else to present.
If you're a student who would like to present a paper during a meeting, you can contact the organizers and sign up for 1 credit of Stat 600.

(03/11, 5-6 PM) Presentation by Alex Kokot. In this talk, we will build on the kernel thinning framework, extending it to coreset problems for non MMD divergences, with entropic optimal transport (particularly the sinkhorn divergence) being our motivating example. Along the way, we introduce basic key properties of entropic optimal transport, and expose how they relate to an implicit dimension reduction induced by this smoothing of the Wasserstein distance. Hybrid in CS&SS Conference Room (Padelford Hall lower level) or via Zoom link here
