Multiplicative Weights Updates as a distributed constrained optimization algorithm: Convergence to second-order stationary points almost always

Ioannis Panageas, Georgios Piliouras, Xiao Wang

Abstract

Non-concave maximization has been the subject of much recent study in the optimization and machine learning communities, specifically in deep learning. Recent papers ([Ge et al. 2015, Lee et al 2017] and references therein) indicate that first order methods work well and avoid saddles points. Results as in [Lee \etal 2017], however, are limited to the
