Research Group and Projects

Lab for Natural Language Processing, and
Center for Language and Speech Processing

Dissertation project (STIMULATE): Maximum Entropy Language Modeling with Non-local Dependencies for Speech Recognition supported by NSF.
So far I have successfully incorporated topic dependencies and syntactic dependencies with N-grams in one unified framework. I proposed fast training methods for ME models. I am implementing an ME toolkit for general purposes with speed-up.
Research Advisor: Prof. Sanjeev Khudanpur
Academic Advisors: Prof. Fred Jelinek and Prof. David Yarowsky

Qualification projects: Part-of-Speech Tagging directed by Prof. Eric Brill and Topic Sensitive Language Modeling directed by Prof. Sanjeev Khudanpur and Prof. Fred Jelinek.

Project at AT&T was on Dialogue System directed by Dr. Roberto Pieraccini and Dr. Esther Levin .

Projects in China was on Continuous Speech Recognition and Telephone Speech Recognition.

Interest Areas

Speech Recognition, particularly language modeling.
Natural Language Processing, particularly for information retrieval.
