Euclid in a Taxicab: Sparse Blind Deconvolution with Smoothed l1/l2 Regularization
Audrey Repetti, Mai Quyen Pham, Laurent Duval +2
The l1/l2 ratio regularization function has shown good performance for retrieving sparse signals in a number of recent works, in the context of blind deconvolution. Indeed, it bene…
A forward-backward view of some primal-dual optimization methods in image recovery
Patrick L. Combettes, Laurent Condat, Jean-Christophe Pesquet +1
A wide array of image recovery problems can be abstracted into the problem of minimizing a sum of composite convex functions in a Hilbert space. To solve such problems, primal-dual…
A Class of Randomized Primal-Dual Algorithms for Distributed Optimization
Jean-Christophe Pesquet, Audrey Repetti
Based on a preconditioned version of the randomized block-coordinate forward-backward algorithm recently proposed in [Combettes,Pesquet,2014], several variants of block-coordinate…
