In plain words: This system squeezes text into a short code and rebuilds it by processing the whole sentence at once, instead of the usual word-by-word networks, keeping a step-by-step model only for writing. It trains and runs faster, handles longer sentences, and avoids earlier training troubles.

Abstract

In this paper we explore the effect of architectural choices on learning a Variational Autoencoder (VAE) for text generation. In contrast to the previously introduced VAE model for text where both the encoder and decoder are RNNs, we propose a novel hybrid architecture that blends fully feed-forward convolutional and deconvolutional components with a recurrent language model. Our architecture exhibits several attractive properties such as faster run time and convergence, ability to better handle long sequences and, more importantly, it helps to avoid some of the major difficulties posed by training VAE models on textual data.
