An Odd Estimator for Shapley Values (Teal Witter, CMC)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: The Shapley value is a ubiquitous framework for attribution in machine learning, encompassing feature importance, data valuation, and causal inference. However, its exact computation is generally intractable, necessitating efficient […]

Hecke algebras and motives (Robert Cass, CMC)
Estella 2099Hecke algebras play a central role in both number theory and representation theory. While some Hecke algebras have explicit descriptions in terms of generators and relations, others are understood through structure constants that encode multiplicities in tensor products of representations. In this talk, I will discuss several projects with Thibaud van den Hove and Jakob […]

A Regularity Criterion for the 3-D Navier-Stokes Equations Based on Finitely Many Observations (Abhishek Balakrishna, USC)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: This talk presents a regularity criterion for the three-dimensional Navier–Stokes equations based on finitely many observations of the flow. Motivated by data assimilation, we study a nudging algorithm that […]

Computing certificates for complete positivity (Achill Schürmann, University of Rostock)
Estella 2099A key problem in computer proofs based on solutions from copositive optimization, is checking whether or not a given quadratic form is completely positive or not. In this talk we describe the first known algorithm for arbitrary rational input. It is based on a suitable adaption of Voronoi's Algorithm and the underlying theory from positive definite […]

Analysis Seminar: Metrics on quantum channels from noncommutative geometry (Tron Omland, University of Oslo and Norwegian National Security Authority)
Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesAbstract: We study metrics on completely positive maps, and in particular on quantum channels, induced by seminorms from noncommutative geometry. Using an infinite-dimensional analogue of the Choi–Jamiołkowski correspondence, we construct […]

The Euler Equations in Function Spaces of Generalized Smoothness (Zachary Radke, OSU)
Emmy Noether Room, Estella 1021, Pomona College, 610 N. College Ave., Claremont, CA, United StatesAbstract: In this talk, we will describe a well/ill-posedness result for the 2D incompressible Euler equations. We investigate solutions in a setting logarithmically smoother than previously done, in a hope to identify the key dynamics leading to a breakdown of regularity in 2D fluid flow. When order of the logarithmic derivative is sufficiently large one […]

Central moments of autocorrelation demerit factors of binary sequences (Daniel Katz, CSUN)
Estella 2099A low autocorrelation binary sequence of length $\ell$ is an $\ell$-tuple of $+1$s and $-1$s that does not strongly resemble any translate of itself. Such sequences are used in communications and remote sensing for synchronization and ranging, where translation represents time delay. A single number that indicates how good a sequence is for such purposes, […]

Analysis Seminar: Restricted isometries and operator norms on finite-dimensional $L^p$-spaces (Alonso Delfín Ares de Parga, CU Boulder)
Estella 2099, Pomona College 610 N. College Ave., Claremont, CA, United StatesAbstract: An isometry between two normed vector spaces is a linear map that preserves the norm (i.e., the length of each output agrees with the length of its input). For the classical $p$-norms, isometries have a very concrete description when $p\neq 2$: they are given by signed permutations of the coordinates. In this talk, I […]
