Copy Code Copy CommandThis example shows how to train stacked autoencoders to classify images of digits. Neural networks with multiple hidden layers can be useful for solving classification problems with complex data, such as images. Each layer can learn features at a different level of abstraction...

Variational autoencoders impose a second constraint on how to construct the hidden representation. Now the latent code has a prior distribution defined by design $p(x)$. In other words, the encoder can not use the entire latent space freely but has to restrict the hidden codes produced to ...
