Guidance in Diffusion Models via Doob’s h-Transform
Abstract: Guidance methods are widely used to adapt pretrained diffusion models to specific objectives, such as conditional generation, inverse problems, or reward-guided generation. In this talk, I will explain how such methods can be understood through Doob’s h-transform, which modifies the sampling dynamics to produce a desired target distribution. I will then discuss how the corresponding h-function and guidance term can be approximated or learned in practice, together with some theoretical guarantees.
