FedDR -- Randomized Douglas-Rachford Splitting Algorithms for Nonconvex Federated Composite Optimization

Quoc Tran-Dinh, Nhan H. Pham, Dzung T. Phan +1

We develop two new algorithms, called, FedDR and asyncFedDR, for solving a fundamental nonconvex composite optimization problem in federated learning. Our algorithms rely on a nove…

An Optimal Hybrid Variance-Reduced Algorithm for Stochastic Composite Nonconvex Optimization

Deyi Liu, Lam M. Nguyen, Quoc Tran-Dinh

In this note we propose a new variant of the hybrid variance-reduced proximal gradient method in [7] to solve a common stochastic composite nonconvex optimization problem under sta…
