Vandermonde Matrices are Merely Exponentially Ill-Conditioned

I am excited to share that my paper Does block size matter in randomized block Krylov low-rank approximation? has recently been released on arXiv. In that paper, we study the randomized block Krylov iteration (RBKI) algorithm for low-rank approximation. Existing results show that RBKI is efficient at producing rank- approximations with a large block size Read more
