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.
