Composite and Stochastic Smoothed Decentralized Bregman Proximal-Gradient Methods

Shengze Xu, Chenhan Jin, Qingsong Wang +1

Smoothed decentralized Bregman proximal-gradient (SDBPG) methods combine relative-smoothness geometry with edge-dual consensus. We extend SDBPG to node-specific convex nonsmooth re…
