Deflation as a Method of Variance Reduction for Estimating the Trace of a Matrix Inverse
Arjun Singh Gambhir, Andreas Stathopoulos, Kostas Orginos
Many fields require computing the trace of the inverse of a large, sparse matrix. The typical method used for such computations is the Hutchinson method which is a Monte Carlo (MC)…
