Deep dives
Evolution of Reinforcement Learning from Human Feedback
Reinforcement learning from human feedback (RLHF) techniques have advanced significantly, with a focus on preference fine-tuning algorithms. While still far from fully replicating GPT's fine-tuning process, RLHF has shown progress in various avenues, particularly in safety tasks like LAMA2. These methods enhance language models to address tasks they shouldn't answer, emphasizing safety and verifiable claims.
