A flow-based generative model is a generative model used in machine learning that explicitly models a probability distribution by leveraging normalizing flow, which is a statistical method using the change-of-variable law of probabilities to transform a simple distribution into a complex one. The direct … See more Let $${\displaystyle z_{0}}$$ be a (possibly multivariate) random variable with distribution $${\displaystyle p_{0}(z_{0})}$$. For $${\displaystyle i=1,...,K}$$, let The log likelihood of See more As is generally done when training a deep learning model, the goal with normalizing flows is to minimize the Kullback–Leibler divergence between the model's likelihood and the target … See more Despite normalizing flows success in estimating high-dimensional densities, some downsides still exist in their designs.

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 ...
