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…
One-Point Sampling for Distributed Bandit Convex Optimization with Time-Varying Constraints
Kunpeng Zhang, Lei Xu, Xinlei Yi +4
This paper considers the distributed bandit convex optimization problem with time-varying constraints. In this problem, the global loss function is the average of all the local con…
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…
