WebAug 7, 2024 · Normalizing flows are a general mechanism that allows us to model complicated distributions, when we have access to a simple one. They have been applied to problems of variational inference, where they can serve as flexible approximate posteriors [1, 2, 3], and also for density estimation, particularly applied to image data [4, 5].
