WebNov 13, 2024 · Classifier-free Guidance overview. Classifier-free Guidance is a way of steering the outputs of Diffusion models to better align with a given input. It is a key aspect of how we are able to type in a text prompt and get back a relevant, generated image. CFG was needed because, by default, a Diffusion model starts from pure noise and randomly ...

Based on the Bayes rule, the p (y x) can be written as p (x y)*p (y)/p (x). The derivation of the formula on x is p (x y)’/p (x)’ which get rid of the p (y) term.
