Stochastic optimization with momentum: convergence, fluctuations, and traps avoidance

A. Barakat, P. Bianchi, W. Hachem +1

In this paper, a general stochastic optimization procedure is studied, unifying several variants of the stochastic gradient descent such as, among others, the stochastic heavy ball…

Sparse Signal Reconstruction for Nonlinear Models via Piecewise Rational Optimization

Arthur Marmin, Marc Castella, Jean-Christophe Pesquet +1

We propose a method to reconstruct sparse signals degraded by a nonlinear distortion and acquired at a limited sampling rate. Our method formulates the reconstruction problem as a…
