In particular, we can transform data to a simple noise distribution with a continuous-time stochastic process described by an SDE. target 9 lives cat foodWebthe paper discusses a new learning principle of score-matching in the context of generative models. while score-matching is a pretty classical idea, the paper nicely demonstrates its power on large scale generative models and addresses the unique challenges posed up modern images. target 9 off easter clearance

"WebAbstract: Existing generative models are typically based on explicit representations of probability distributions (e.g., autoregressive or VAEs) or implicit sampling procedures (e.g., GANs). We propose an alternative approach based on modeling directly the vector field of gradients of the data distribution (scores). " - Generative modeling by estimating gradients
