An Edge-based Stochastic Proximal Gradient Algorithm for Decentralized Composite Optimization

This paper investigates decentralized composite optimization problems involving a common non-smooth regularization term over an undirected and connected network. In the same situation, there exist lots of gradient-based proximal distributed methods, but most of them are only sublinearly convergent....
