RESEARCH INTERESTS
- Speech and Language Processing (speech recognition and understanding, speaker recognition, natural language processing)
- Statistical Machine Intelligence (particularly with probabilistic graphical models and deep learning)
I'm broadly interested in Dealing with Uncertainty for Intelligent Systems. The two fundamental problems are first to construct probabilistic models of the studied phenomenon using human knowledge and machine learning algorithms, and second to find efficient ways of implementing probabilistic inference with those models. Graphical models have emerged as a general framework for describing and applying probabilistic models, while the core is probability theory and mathematical statistics.
Current interests are Speech and Language Processing, by proposing new models of speech and language, developing new methods for learning and inference with those models, and applying them to real tasks in speech and language processing. 100,000 years ago, humans started to speak so they could free up their hands. Is it going to happen again? Getting rid of keyboards and talking to machines is not a dream in the near future, I believe. Moreover, efficient searching, mining, and browsering the large amounts of digital media, in which speech is often an indispensable component, also needs speech signal and information processing techniques.
