About Me

I am a Ph.D. student at Computer Science of the University of Hong Kong (HKU), working with Prof. Yiu, Siu Ming.

My research interests mainly focus on topic modeling, lexically constrained text generation and information retrieval. In short, topic modeling is meant to infer the latent topics from the given documents; lexically constrained text generation aims to generate plausible and grammatical sentences under the given keywords; and information retrieval is to fetch top relevant documents from a huge collection for the input query.
