Variable metric inexact line-search based methods for nonsmooth optimization
Silvia Bonettini, Ignace Loris, Federica Porta +1
We develop a new proximal-gradient method for minimizing the sum of a differentiable, possibly nonconvex, function plus a convex, possibly non differentiable, function. The key fea…
A blind deconvolution method for ground based telescopes and Fizeau interferometers
M. Prato, A. La Camera, S. Bonettini +3
In the case of ground-based telescopes equipped with adaptive optics systems, the point spread function (PSF) is only poorly known or completely unknown. Moreover, an accurate mode…
A cyclic block coordinate descent method with generalized gradient projections
Silvia Bonettini, Marco Prato, Simone Rebegoldi
The aim of this paper is to present the convergence analysis of a very general class of gradient projection methods for smooth, constrained, possibly nonconvex, optimization. The k…
