Research interest

I am working on natural language processing and deep generative models. I have particular interests in neural conversation system and text generation.

Specifically,

1). Deep generative model for text generation.

2). Improving sequence-to-sequence training with sentence-level objectives.

3). Generating neural responses with speaker consistency and external knowledge.

4). Intent-tracking mechanism for open-domain conversational agent.

5). Interplays between deep learning, sampling and NLP.
