RLHF Explained: How AI Learns Human Preferences

Reinforcement Learning from Human Feedback (RLHF) is a technique used to train AI models to be more helpful and aligned with human preferences. This process involves humans ranking different AI-generated responses, which are then used to train a reward model. Finally, the AI model is fine-tuned based on the feedback from this reward model to improve its helpfulness. AI
