===== RLHF =====
RLHF: Reinforcement Learning with Human Feedback.  This definition is quite general, and would apply to any method of reinforcement learning with human feedback.  Actually RLHF usually refers to a specific method of doing this.  For a quick a overview, see section 3 of [[https://arxiv.org/pdf/2305.18290.pdf|Rafailov 2023]].
