Leftover Lunch: Advantage-based Offline Reinforcement Learning for Language Models

Ashutosh Baheti, Ximing Lu, Faeze Brahman +3

Reinforcement Learning with Human Feedback (RLHF) is the most prominent method for Language Model (LM) alignment. However, RLHF is an unstable and data-hungry process that continua…
