Modified Fejér sequences and applications

Junhong Lin, Lorenzo Rosasco, Silvia Villa +1

In this note, we propose and study the notion of modified Fejér sequences. Within a Hilbert space setting, we show that it provides a unifying framework to prove convergence rates…

Stochastic inertial primal-dual algorithms

Lorenzo Rosasco, Silvia Villa, Bang Cong Vu

We propose and study a novel stochastic inertial primal-dual approach to solve composite optimization problems. These latter problems arise naturally when learning with penalized r…

A stochastic inertial forward-backward splitting algorithm for multivariate monotone inclusions

Lorenzo Rosasco, Silvia Villa, Bang Cong Vu

We propose an inertial forward-backward splitting algorithm to compute the zero of a sum of two monotone operators allowing for stochastic errors in the computation of the operator…

Learning Multiple Visual Tasks while Discovering their Structure

Carlo Ciliberto, Lorenzo Rosasco, Silvia Villa

Multi-task learning is a natural approach for computer vision applications that require the simultaneous solution of several distinct but related problems, e.g. object detection, c…

Consistent Learning by Composite Proximal Thresholding

Patrick L. Combettes, Saverio Salzo, Silvia Villa

We investigate the modeling and the numerical solution of machine learning problems with prediction functions which are linear combinations of elements of a possibly infinite-dimen…
