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…

Accelerating Multi-Task Temporal Difference Learning under Low-Rank Representation

Yitao Bai, Sihan Zeng, Justin Romberg +1

We study policy evaluation problems in multi-task reinforcement learning (RL) under a low-rank representation setting. In this setting, we are given learning tasks where the co…
