Distributed Stochastic Optimization for Non-Smooth and Weakly Convex Problems under Heavy-Tailed Noise
Jun Hu, Chao Sun, Bo Chen +2
In existing distributed stochastic optimization studies, it is usually assumed that the gradient noise has a bounded variance. However, recent research shows that the heavy-tailed…

Covariance-Intersection-based Distributed Kalman Filtering: Stability Problems Revisited
Zhongyao Hu, Bo Chen, Chao Sun +1
This paper studies the stability of covariance-intersection (CI)-based distributed Kalman filtering in time-varying systems. For the general time-varying case, a relationship betwe…
