Title:
What are the limits of large random matrices? And what does this say about algorithms?
Abstract:
Random matrix theory has played a major role in several areas of pure and applied mathematics, as well as statistics, physics, and computer science. This lecture aims to describe phenomena where large random matrices can be described by certain limiting operators, and how this provides new easy-to-use sharp non-asymptotic bounds on the spectrum of general random matrices. We will use Tensor PCA and the Kikuchi algorithm for it, as a running example where the arising limit operators are a central object in noncommutative probability, functioning as a hybrid between commutative and free variables.
This talk is meant to a broad mathematical audience, no previous background in Random Matrix Theory or noncommutative probability is assumed.
