The Lanczos algorithm for matrix functions: a handbook for scientists
Tyler Chen
Lanczos-based methods have become standard tools for tasks involving matrix functions. Progress on these algorithms has been driven by several largely disjoint communities, resulti…

Near-optimal hierarchical matrix approximation from matrix-vector products
Tyler Chen, Feyza Duman Keles, Diana Halikias +3
We describe a randomized algorithm for producing a near-optimal hierarchical off-diagonal low-rank (HODLR) approximation to an matrix , accessible only thou…

Fixed-sparsity matrix approximation from matrix-vector products
Noah Amsel, Tyler Chen, Feyza Duman Keles +3
We study the problem of approximating a matrix with a matrix that has a fixed sparsity pattern (e.g., diagonal, banded, etc.), when is accessed only by ma…
