A Comprehensive Introduction to Reinforcement Learning from Human Feedback (RLHF)

  • Reinforcement Learning from Human Feedback (RLHF) is crucial for aligning large language models with human intent, seen in models like ChatGPT and Claude.
  • RLHF uses human feedback to guide models towards desired behavior, moving beyond traditional supervised learning.
  • RLHF involves a three-phase pipeline that enables models to iteratively improve based on human-preferred behavior.
  • Through techniques like Proximal Policy Optimization (PPO), RLHF optimizes language models by generating responses aligned with human preferences.
