Before revision:  We demonstrate excellent perplexity (PPL) results on several datasets, and show that the framework learns a rich latent space, allowing for interpolation between sentences of different lengths with a fixed-dimensional latent representation.
After revision:  We demonstrate excellent perplexity (PPL) results on several datasets, and show that the framework learns a rich latent space, comparable to VAEs. The structured latent representation is demonstrated with interpolation between sentences of different lengths with a fixed-dimensional latent representation.
