Score-based Generative Modeling in Latent Space Research

WebScore-based generative model (SGM) do this by employing two stochastic differential equations (SDEs). The first one is called the forward SDE. It can take very general forms, but a popular choice is the Ornstein-Uhlenbeck process. dXt = −1 2Xtdt+dW t, X0 ∼ μdata. (1) (1) d X t = − 1 2 X t d t + d W t, X 0 ∼ μ data. WebScore-based generative models (SGMs) need to approximate the scores ∇logpt ∇ log p t of the intermediate distributions as well as the final distribution pT p T of the forward process. The theoretical underpinnings of the effects of these approximations are still lacking. We find precise conditions under which SGMs are able to produce ...
