What does RLHF mean?
RLHF stands for Reinforcement Learning from Human Feedback. It is a machine learning technique used to align AI systems with human preferences through iterative training.
Core answer
Answer
This method involves collecting human feedback on AI responses, typically as comparisons or rankings. These preferences train a reward model that predicts desirable outcomes. Using reinforcement learning, the AI policy is then fine-tuned to maximize rewards from this human-derived model, leading to more helpful, accurate, and safe outputs.
RLHF significantly enhances AI systems like large language models by making them more useful and controllable for users. It refines outputs to better follow instructions, reduce misinformation, align with ethics, and increase real-world application viability across chatbots, content generation, and research assistance.
