A preconditioned inverse iteration with an improved convergence guarantee

Foivos Alimisis, Daniel Kressner, Nian Shao +1

Preconditioned eigenvalue solvers offer the possibility to incorporate preconditioners for the solution of large-scale eigenvalue problems, as they arise from the discretization of…

A Nesterov-style Accelerated Gradient Descent Algorithm for the Symmetric Eigenvalue Problem

Foivos Alimisis, Simon Vary, Bart Vandereycken

We develop an accelerated gradient descent algorithm on the Grassmann manifold to compute the subspace spanned by a number of leading eigenvectors of a symmetric positive semi-defi…
