Variance-Reduced Policy Gradient Approaches for Infinite Horizon Average Reward Markov Decision Processes

no code implementations2 Apr 2024 Swetha Ganesh, Washim Uddin Mondal, Vaneet Aggarwal

The second approach, rooted in Hessian-based techniques, ensures an expected regret of the order $\tilde{\mathcal{O}}(\sqrt{T})$.

Global Convergence Guarantees for Federated Policy Gradient Methods with Adversaries

no code implementations15 Mar 2024 Swetha Ganesh, Jiayu Chen, Gugan Thoppe, Vaneet Aggarwal

Federated Reinforcement Learning (FRL) allows multiple agents to collaboratively build a decision making policy without sharing raw trajectories.

Online Learning with Adversaries: A Differential-Inclusion Analysis

no code implementations4 Apr 2023 Swetha Ganesh, Alexandre Reiffers-Masson, Gugan Thoppe

Our main result is that the proposed algorithm almost surely converges to the desired mean $\mu.$ This makes ours the first asynchronous FL method to have an a. s. convergence guarantee in the presence of adversaries.
