Scores as Actions: a framework of fine-tuning diffusion models by continuous-time reinforcement learning
Hanyang Zhao, Haoxian Chen, Ji Zhang +2
Reinforcement Learning from human feedback (RLHF) has been shown a promising direction for aligning generative models with human intent and has also been explored in recent works f…
