Continuous-Time Decentralized Online Estimation With Additive Noises
Xiaozheng Fu, Yan Chen, Tao Li
We study a decentralized online estimation problem with additive communication noises over the fixed digraph. Each node has a linear measurement of an unknown parameter with random…
Decentralized Online Learning for Random Inverse Problems Over Graphs
Xiwei Zhang, Tao Li, Yan Chen +1
We propose a decentralized online learning algorithm for distributed random inverse problems over network graphs with online measurements, and unifies the distributed parameter est…
Online Regularized Statistical Learning in Reproducing Kernel Hilbert Space With Non-Stationary Data
Xiwei Zhang, Yan Chen, Tao Li
We study recursive regularized learning algorithms in the reproducing kernel Hilbert space (RKHS) with non-stationary online data streams. We introduce the concept of a random Tikh…
Graphon Particle Systems, Part II: Dynamics of Distributed Stochastic Continuum Optimization
Yan Chen, Tao Li, Xiaofeng Zong
We study the distributed optimization problem over a graphon with a continuum of nodes, which is regarded as the limit of the distributed networked optimization as the number of no…
Graphon Particle Systems, Part I: Spatio-Temporal Approximation and Law of Large Numbers
Yan Chen, Tao Li, Xiaofeng Zong
We study a class of graphon particle systems with time-varying random coefficients. In a graphon particle system, the interactions among particles are characterized by the coupled…
