Convergence of Decentralized Stochastic Subgradient-based Methods for Nonsmooth Nonconvex functions
Siyuan Zhang, Nachuan Xiao, Xin Liu
In this paper, we focus on the decentralized stochastic subgradient-based methods in minimizing nonsmooth nonconvex functions without Clarke regularity, especially in the decentral…
