Offline Multitask Representation Learning for Reinforcement Learning

Haque Ishfaq, Thanh Nguyen-Tang, Songtao Feng +4

We study offline multitask representation learning in reinforcement learning (RL), where a learner is provided with an offline dataset from different tasks that share a common repr…

Improving Sample Efficiency of Model-Free Algorithms for Zero-Sum Markov Games

Songtao Feng, Ming Yin, Yu-Xiang Wang +2

The problem of two-player zero-sum Markov games has recently attracted increasing interests in theoretical studies of multi-agent reinforcement learning (RL). In particular, for fi…

Non-stationary Reinforcement Learning under General Function Approximation

Songtao Feng, Ming Yin, Ruiquan Huang +3

General function approximation is a powerful tool to handle large state and action spaces in a broad range of reinforcement learning (RL) scenarios. However, theoretical understand…

Adaptive Coding for Information Freshness in a Two-user Broadcast Erasure Channel

Songtao Feng, Jing Yang

In this paper, we investigate the impact of coding on the Age of Information (AoI) in a two-user broadcast symbol erasure channel with feedback. We assume each update consists of $…
