Convergence of LCA Flows to (C)LASSO Solutions
Ping Tak Peter Tang
This paper establishes several convergence results about flows of the dynamical system LCA (Locally Competitive Algorithm) to the mixed - minimization problem LASSO…
FEAST Eigensolver for non-Hermitian Problems
James Kestyn, Eric Polizzi, Ping Tak Peter Tang
A detailed new upgrade of the FEAST eigensolver targeting non-Hermitian eigenvalue problems is presented and thoroughly discussed. It aims at broadening the class of eigenproblems…
Zolotarev Quadrature Rules and Load Balancing for the FEAST Eigensolver
Stefan Guettel, Eric Polizzi, Ping Tak Peter Tang +1
The FEAST method for solving large sparse eigenproblems is equivalent to subspace iteration with an approximate spectral projector and implicit orthogonalization. This relation all…
A New Highly Parallel Non-Hermitian Eigensolver
Ping Tak Peter Tang, James Kestyn, Eric Polizzi
Calculating portions of eigenvalues and eigenvectors of matrices or matrix pencils has many applications. An approach to this calculation for Hermitian problems based on a density…
FEAST as a Subspace Iteration Eigensolver Accelerated by Approximate Spectral Projection
Ping Tak Peter Tang, Eric Polizzi
The calculation of a segment of eigenvalues and their corresponding eigenvectors of a Hermitian matrix or matrix pencil has many applications. A new density-matrix-based algorithm…
