What is ‘RLHF’ (Reinforcement Learning from Human Feedback) and how does it address alignment?

Accepted Answer

RLHF (Reinforcement Learning from Human Feedback) uses human preference rankings to train a reward model, then applies RL to optimize the AI's outputs towards human-preferred responses. This methodology directly involves human feedback in the training process to align AI behavior with human preferences.
