We saw in a previous post how the Kullback-Leibler divergence influence a VAE’s encoder and decoder outputs. In particular, we could notice that whereas the encoder outputs are closer to a standard multivariate normal distribution thanks to the KL divergence, the result is far from being perfect and there are still some gaps. The Adversarial Autoencoder tends to fix that problem by using a Generative Adversarial Network rather than the KL divergence.
