Distributed risk-averse optimization via CVaR
Siyi Wang, Kun Huang, Lei Xu +1
Distributed systems often operate under uncertainty, where minimizing expected loss may overlook rare but severe events. This paper studies a distributed risk-averse convex optimiz…
Achieving Linear Speedup for Composite Federated Learning
Kun Huang, Shi Pu, Karl Henrik Johansson
This paper proposes FedNMap, a normal map-based method for composite federated learning, where the objective consists of a smooth loss and a possibly nonsmooth regularizer. FedNMap…
Distributed Stochastic Momentum Tracking with Local Updates: Achieving Optimal Communication Complexities
Kun Huang, Shi Pu
We propose Local Momentum Tracking (LMT), a novel distributed stochastic gradient method for solving distributed optimization problems over networks. To reduce communication overhe…
Decentralized Min-Max Optimization with Gradient Tracking
Runze You, Kun Huang, Shi Pu
This paper presents a novel distributed formulation of the min-max optimization problem. Such a formulation enables enhanced flexibility among agents when optimizing their maximiza…
Distributed Normal Map-based Stochastic Proximal Gradient Methods over Networks
Kun Huang, Shi Pu, Angelia Nedić
