The answer
A rating can become feedback data, but RLHF requires a training process that turns feedback into optimization signals. Clicking a button does not itself update model parameters.
What is reinforcement learning with human feedback (RLHF)?
Is RLHF the same as a user clicking thumbs up?
More FAQs in What is reinforcement learning with human feedback (RLHF)?
No. Some approaches, including standard DPO, directly optimize preference comparisons without a separately trained explicit reward model or the classic PPO training loop.
No. Feedback can discourage unsupported answers and improve some behaviors, but imperfect supervision and reward models can still leave confident mistakes and misleading outputs.
