Continuous-time Analysis of a Stochastic ADMM Method for Nonconvex Composite Optimization
In this paper, we focus on nonconvex composite optimization, whose objective is the sum of a smooth but possibly nonconvex function and a composition of a weakly convex function coupled with a linear operator. By leveraging a smoothing technique based on Moreau envelope, we propose a stochastic proximal linearized ADMM algorithm (SPLA). To understand its … Read more
