On the Linear Speedup of Personalized Federated Reinforcement Learning with Shared Representations

Guojun Xiong, Shufan Wang, Daniel Jiang +1

Federated reinforcement learning (FedRL) enables multiple agents to collaboratively learn a policy without sharing their local trajectories collected during agent-environment inter…

DOPL: Direct Online Preference Learning for Restless Bandits with Preference Feedback

Guojun Xiong, Ujwal Dinesha, Debajoy Mukherjee +2

Restless multi-armed bandits (RMAB) has been widely used to model constrained sequential decision making problems, where the state of each restless arm evolves according to a Marko…

Decentralized Federated Learning with Model Caching on Mobile Agents

Xiaoyu Wang, Guojun Xiong, Houwei Cao +2

Federated Learning (FL) trains a shared model using data and computation power on distributed agents coordinated by a central server. Decentralized FL (DFL) utilizes local model ex…

Provably Efficient Reinforcement Learning for Adversarial Restless Multi-Armed Bandits with Unknown Transitions and Bandit Feedback

Guojun Xiong, Jian Li

Restless multi-armed bandits (RMAB) play a central role in modeling sequential decision making problems under an instantaneous activation constraint that at most B arms can be acti…

Structured Reinforcement Learning for Delay-Optimal Data Transmission in Dense mmWave Networks

Shufan Wang, Guojun Xiong, Shichen Zhang +3

We study the data packet transmission problem (mmDPT) in dense cell-free millimeter wave (mmWave) networks, i.e., users sending data packet requests to access points (APs) via upli…
