Before revision:  We construct a sequential , neural variational autoencoder that uses a carefully defined encoder, and Gumbel-Softmax reparametrization, to allow for successful backpropagation during training.
After revision:  We construct a sequential , neural variational autoencoder , which uses Gumbel-Softmax reparametrization within a carefully defined encoder, and Gumbel-Softmax reparametrization, to allow for successful backpropagation during training.
