A federated Kaczmarz algorithm
Halyun Jeong, Deanna Needell, Chi-Hao Wu
In this paper, we propose a federated algorithm for solving large linear systems that is inspired by the classic randomized Kaczmarz algorithm. We provide convergence guarantees of…

A quantitative dichotomy for Lyapunov exponents of non-dissipative SDEs with an application to electrodynamics
Jacob Bedrossian, Chi-Hao Wu
In this paper we derive a quantitative dichotomy for the top Lyapunov exponent of a class of non-dissipative SDEs on a compact manifold in the small noise limit. Specifically, we p…
