Task: Summarization
Input (English): Recurrent models for sequences have been recently successful at many tasks, especially for language modeling
 and machine translation. Nevertheless, it remains challenging to extract good representations from
 these models. For instance, even though language has a clear hierarchical structure going from characters
 through words to sentences, it is not apparent in current language models.
 We propose to improve the representation in sequence models by
 augmenting current approaches with an autoencoder that is forced to compress
 the sequence through an intermediate discrete latent space. In order to propagate gradients
 though this discrete representation we introduce an improved semantic hashing technique.
 We show that this technique performs well on a newly proposed quantitative efficiency measure.
 We also analyze latent codes produced by the model showing how they correspond to
 words and phrases. Finally, we present an application of the autoencoder-augmented
 model to generating diverse translations.
Output (English): Autoencoders for text with a new method for using discrete latent space.
