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…
Distributed Seeking for Fixed Points of Biased Stochastic Operators: A Communication-Efficient Approach
Fan Li, Lei Xu, Xinlei Yi +3
This paper investigates the distributed fixed point seeking problem of sum-separable stochastic operators over the multi-agent network. Based on inexact Krasnosel'ski\uı--Mann iter…
Communication-Efficient Distributed Online Nonconvex Optimization with Time-Varying Constraints
Kunpeng Zhang, Lei Xu, Xinlei Yi +5
This paper considers distributed online nonconvex optimization with time-varying inequality constraints over a network of agents, where the nonconvex local loss and convex local co…
Distributed Constrained Online Nonconvex Optimization with Compressed Communication
Kunpeng Zhang, Lei Xu, Xinlei Yi +4
This paper considers distributed online nonconvex optimization with time-varying inequality constraints over a network of agents. For a time-varying graph, we propose a distributed…
Compressed Gradient Tracking Algorithms for Distributed Nonconvex Optimization
Lei Xu, Xinlei Yi, Guanghui Wen +3
In this paper, we study the distributed nonconvex optimization problem, which aims to minimize the average value of the local nonconvex cost functions using local information excha…
