Coordinate projected gradient descent minimization and its application to orthogonal nonnegative matrix factorization
Flavia Chorobura, Daniela Lupu, Ion Necoara
In this paper we consider large-scale composite nonconvex optimization problems having the objective function formed as a sum of three terms, first has block coordinate-wise Lipsch…
An adaptive forward-backward-forward splitting algorithm for solving pseudo-monotone inclusions
Flavia Chorobura, Ion Necoara, Jean-Christophe Pesquet
In this paper, we propose an adaptive forward-backward-forward splitting algorithm for finding a zero of a pseudo-monotone operator which is split as a sum of three operators: the…
Coordinate descent methods beyond smoothness and separability
Flavia Chorobura, Ion Necoara
This paper deals with convex nonsmooth optimization problems. We introduce a general smooth approximation framework for the original function and apply random (accelerated) coordin…
Random coordinate descent methods for nonseparable composite optimization
Flavia Chorobura, Ion Necoara
In this paper we consider large-scale composite optimization problems having the objective function formed as a sum of two terms (possibly nonconvex), one has (block) coordinate-wi…
Efficiency of stochastic coordinate proximal gradient methods on nonseparable composite optimization
I. Necoara, F. Chorobura
This paper deals with composite optimization problems having the objective function formed as the sum of two terms, one has Lipschitz continuous gradient along random subspaces and…
