Robust Policy Expansion for Offline-to-Online RL under Diverse Data Corruption

Longxiang He, Deheng Ye, Junbo Tan +2

Pretraining a policy on offline data followed by fine-tuning through online interactions, known as Offline-to-Online Reinforcement Learning (O2O RL), has emerged as a promising par…

AlignIQL: Policy Alignment in Implicit Q-Learning through Constrained Optimization

Longxiang He, Li Shen, Xueqian Wang

Implicit Q-learning (IQL) serves as a strong baseline for offline RL, which learns the value function using only dataset actions through quantile regression. However, it is unclear…

DiffCPS: Diffusion Model based Constrained Policy Search for Offline Reinforcement Learning

Longxiang He, Li Shen, Linrui Zhang +2

Constrained policy search (CPS) is a fundamental problem in offline reinforcement learning, which is generally solved by advantage weighted regression (AWR). However, previous meth…
