Learning-Based Low-Rank Approximations - IPAM at UCLA

Explore a 49-minute lecture on learning-based algorithms for low-rank approximation problems presented by Piotr Indyk from the Massachusetts Institute of Technology. Delve into the recent advancements in optimizing algorithm performance using training sets of input matrices. Discover the two-step process of efficient approximate algorithms for computing low-rank approximations, involving the computation of a "sketch" and subsequent singular value decomposition. Learn how replacing random matrices with "learned" matrices significantly reduces approximation errors. Gain insights into joint work with Peter Bartlett, Yang Yuan, Ali Vakilian, Tal Wagner, and David Woodruff in this IPAM workshop on Multi-Modal Imaging with Deep Learning and Modeling.
