STRAPPER: Preference-based Reinforcement Learning via Self-training Augmentation and Peer Regularization

1 code implementation19 Jul 2023 Yachen Kang, Li He, Jinxin Liu, Zifeng Zhuang, Donglin Wang

Due to the existence of similarity trap, such consistency regularization improperly enhances the consistency possiblity of the model's predictions between segment pairs, and thus reduces the confidence in reward learning, since the augmented distribution does not match with the original one in PbRL.

CLUE: Calibrated Latent Guidance for Offline Reinforcement Learning

no code implementations23 Jun 2023 Jinxin Liu, Lipeng Zu, Li He, Donglin Wang

As a remedy for the labor-intensive labeling, we propose to endow offline RL tasks with a few expert data and utilize the limited expert data to drive intrinsic rewards, thus eliminating the need for extrinsic rewards.

Offline Experience Replay for Continual Offline Reinforcement Learning

no code implementations23 May 2023 Sibo Gai, Donglin Wang, Li He

In this paper, we formulate a new setting, continual offline reinforcement learning (CORL), where an agent learns a sequence of offline reinforcement learning tasks and pursues good performance on all learned tasks with a small replay buffer without exploring any of the environments of all the sequential tasks.
