Simon Fraser University
Recently, Sherry et al. (2024) reconsidered the pioneering work of Dahlquist and Jeltsch (1979) on circle-contractivity for the study of neural networks. This theory can be used to analyse and improve the robustness of architectures that are devised...

University of Washington
For many optimization problems, we lack time-efficient algorithms; in many cases this is true even for "average-case" inputs from simple data models. To what extent can tools for complexity theory be adapted to this average-case setting? In this talk...

The classical McKay correspondence shows that there is a bijection between irreducible representations of finite subgroups GG of S L ( 2 , C )SL(2,C) and the exceptional divisors of the minimal resolution of the singularity C 2 / GC2/G. This is a...

A classical theorem of Birch and Merriman states that, for fixed n the set of integral binary n -ic forms with fixed nonzero discriminant breaks into finitely many G L 2 ( Z ) -orbits. In this talk, I’ll present several extensions of this finiteness...

Denoising Diffusion models have revolutionized generative modeling. Conceptually, these methods define a transport mechanism from a noise distribution to a data distribution. Recent advancements have extended this framework to define transport maps...

UW Combinatorics and Geometry Seminar: Lucas Gagnon

Schubert polynomials concretely embody the remarkable connection between the geometry of the flag variety G L ( n ) / B and the combinatorics of the symmetric group. This talk will develop similar story for the forest polynomials recently introduced...

In this talk, we study a variational problem that provides a way to extend minimizing geodesics connecting two given probability measures in the Wasserstein space for all times. This is achieved by allowing negative coefficients in the classical...

Shape analysis is a framework for treating complex data and obtain metrics on spaces of data. Examples are spaces of unparametrized curves, time-signals, surfaces and images. In this talk we discuss structure preservation and deep learning for...

Life is a nonequilibrium phenomenon where nonlocal processes play a prominent and increasingly important role. Nonlocal models have emerged as a robust mathematical framework for capturing interactions across spatial and temporal scales in the life...
