An abstract convergence framework with application to inertial inexact forward--backward methods
Silvia Bonettini, Peter Ochs, Marco Prato +1
In this paper we introduce a novel abstract descent scheme suited for the minimization of proper and lower semicontinuous functions. The proposed abstract scheme generalizes a set…
On the convergence of a linesearch based proximal-gradient method for nonconvex optimization
Silvia Bonettini, Ignace Loris, Federica Porta +2
We consider a variable metric linesearch based proximal gradient method for the minimization of the sum of a smooth, possibly nonconvex function plus a convex, possibly nonsmooth t…
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…
