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…
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…
Online Regularized Statistical Learning in Reproducing Kernel Hilbert Space With Non-Stationary Data
Yan Chen, Tao Li, Xiwei Zhang
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…
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…
