28.09.2018 · In the variational autoencoder, is specified as a standard Normal distribution with mean zero and variance one. If the encoder outputs representations that are different than those from a standard...

In this tutorial we'll give a brief introduction to variational autoencoders (VAE), then show how to build them step-by-step in Keras. Full code included.

24.05.2020 · What is a Variational Autoencoder (VAE)? Typically, the latent space z produced by the encoder is sparsely populated, meaning that it is difficult to predict the distribution of values in that space. Values are scattered and space will appear to be well utilized in a 2D representation. This is a very good property for compression systems.

A Variational Autoencoder is a type of likelihood-based generative model. It consists of an encoder, that takes in data x as input and transforms this into a latent representation z, and a decoder, that takes a latent representation z and returns a reconstruction x ^.

14.05.2020 · In order to train the variational autoencoder, we only need to add the auxillary loss in our training algorithm. The following code is essentially copy-and-pasted from above, with a single term added added to the loss (autoencoder.encoder.kl).
