A Preconditioner for a Primal-Dual Newton Conjugate Gradients Method for Compressed Sensing Problems
Ioannis Dassios, Kimon Fountoulakis, Jacek Gondzio
In this paper we are concerned with the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. We extend…
Robust Block Coordinate Descent
Kimon Fountoulakis, Rachael Tappenden
In this paper we present a novel randomized block coordinate descent method for the minimization of a convex composite objective function. The method uses (approximate) partial sec…
A Second-Order Method for Compressed Sensing Problems with Coherent and Redundant Dictionaries
Ioannis Dassios, Kimon Fountoulakis, Jacek Gondzio
In this paper we are interested in the solution of Compressed Sensing (CS) problems where the signals to be recovered are sparse in coherent and redundant dictionaries. CS problems…
