Finite-Time Analysis of Projected Two-Time-Scale Stochastic Approximation
Yitao Bai, Thinh T. Doan, Justin Romberg
We study the finite-time convergence of projected linear two-time-scale stochastic approximation with constant step sizes and Polyak--Ruppert averaging. We establish an explicit me…
Improved Convergence Rate for a Distributed Two-Time-Scale Gradient Method under Random Quantization
Marcos M. Vasconcelos, Thinh T. Doan, Urbashi Mitra
We study the so-called distributed two-time-scale gradient method for solving convex optimization problems over a network of agents when the communication bandwidth between the nod…
Distributed two-time-scale methods over clustered networks
Thiem V. Pham, Thinh T. Doan, Dinh Hoa Nguyen
In this paper, we consider consensus problems over a network of nodes, where the network is divided into a number of clusters. We are interested in the case where the communication…
