Flow based model文章
WebOct 13, 2024 · Flow-based Deep Generative Models. So far, I’ve written about two types of generative models, GAN and VAE. Neither of them explicitly learns the probability density function of real data, p ( x) (where x ∈ D) — because it is really hard! Taking the generative model with latent variables as an example, p ( x) = ∫ p ( x z) p ( z) d z ...
