keras variational autoencoder loss function
keras variational autoencoder loss function Question: I’ve read this blog by Keras on VAE implementation, where VAE loss is defined this way: def vae_loss(x, x_decoded_mean): xent_loss = objectives.binary_crossentropy(x, x_decoded_mean) kl_loss = – 0.5 * K.mean(1 + z_log_sigma – K.square(z_mean) – K.exp(z_log_sigma), axis=-1) return xent_loss + kl_loss I looked at the Keras documentation and the VAE …
