Correct! Well done.
Incorrect.
The correct answer is B) A training approach where human preferences between model outputs are used to train a reward model, which guides RL fine-tuning for better alignment with human values
B
Correct Answer
A training approach where human preferences between model outputs are used to train a reward model, which guides RL fine-tuning for better alignment with human values
Explanation
RLHF (InstructGPT, ChatGPT): collect human comparisons of outputs → train reward model → use PPO to maximize reward. Dramatically improves instruction following, helpfulness, and reducing harmful outputs.
