Variational autoencoders

Variational autoencoders (VAEs) are built on the idea of the standard autoencoder, and are powerful generative models and one of the most popular means of learning a complicated distribution in an unsupervised fashion. VAEs are probabilistic models rooted in Bayesian inference. A probabilistic model is exactly as it sounds:

Probabilistic models incorporate random variables and probability distributions into the model of an event or phenomenon.

VAEs, and other generative models, are probabilistic in that they seek to learn a distribution that they utilize for subsequent sampling. While all generative models are probabilistic models, not all probabilistic models are generative models.
