Controllable Text Generation With Deep Latent-Variable Models

Abstract: Progress in deep learning has led to optimism for automatic text generation. Yet state-of-the-art systems still predict inaccurate output on a non-trivial percentage of examples. Lack of user control to correct these issues makes it difficult to deploy these models in real applications. In this talk, I will argue that discrete latent-variable models provide a natural declarative framework for more controllable text models. I will present two recent works exploring this theme: (1) a method for learning neural template models that can be adjusted directly by users; (2) a variational approach to soft attention that learns alignment as a latent variable. I will end by discussing research challenges for making it easy to design and fit these models for large scale applications.
