Center node: "paraphrase generation with latent bag of words"
  Abstract: Paraphrase generation is a longstanding important problem in natural language processing. #R##N#In addition, recent progress in deep generative models has shown promising results on discrete latent variables for text generation. #R##N#Inspired by variational autoencoders with discrete latent structures, in this work, we propose a latent bag of words (BOW) model for paraphrase generation. #R##N#We ground the semantics of a discrete latent variable by the BOW from the target sentences. #R##N#We use this latent variable to build a fully differentiable content planning and surface realization model. #R##N#Specifically, we use source words to predict their neighbors and model the target BOW with a mixture of softmax. #R##N#We use Gumbel top-k reparameterization to perform differentiable subset sampling from the predicted BOW distribution. #R##N#We retrieve the sampled word embeddings and use them to augment the decoder and guide its generation search space. #R##N#Our latent BOW model not only enhances the decoder, but also exhibits clear interpretability. #R##N#We show the model interpretability with regard to \emph{(i)} unsupervised learning of word neighbors \emph{(ii)} the step-by-step generation procedure. #R##N#Extensive experiments demonstrate the transparent and effective generation process of this model.\footnote{Our code can be found at \url{this https URL}}
