Faster Linear Systems and Matrix Norm Approximation via Multi-level Sketched Preconditioning

Michał Dereziński, Christopher Musco, Jiaming Yang

We present a new class of preconditioned iterative methods for solving linear systems of the form $A x = b$ . Our methods are based on constructing a low-rank Nyström approximation t…

Solving Dense Linear Systems Faster Than via Preconditioning

Michał Dereziński, Jiaming Yang

We give a stochastic optimization algorithm that solves a dense $n \times n$ real-valued linear system $A x = b$ , returning $x ~$ such that $∥ A x ~ - b ∥ \leq ε ∥ b ∥$ in time: $…
