RESEARCH

Statistical Machine Translation:

 GALE Project (2007-2008)
 Participated in GALE machine translation tasks : Chinese-English Machine Translation Task in 2007, Arabic-English Machine Translation Task in 2008
 Parallelized the training procedure of phrase-based statistical machine translation system
 Parallelized the Word Alignment program (GIZA++)
 Parallelized Phrase Extraction and Feature Estimation procedure on Hadoop platform
 Improved the efficiency of SMT training procedure from than one week to less than 2 days by combining both of the new technologies.
 Proposed and implemented corpus re-sampling technology using monolingual language models
 NIST Machine Translation Evaluation (2005)
 Implemented word based statistical machine translation decoder, added simulation annealing to the greedy algorithm.

Speech Recognition

 Designed and implemented the PULSAR decoder based on Weighted Finite State Transducer and models from SphinxTrain. (2003-2006)
 Participated in building CASA-Based speech separation system, responsible for the pitch tracking and spectrum re-construction modules.(2006)
 Proposed and implemented fast latent semantic adaptation for language models using automatically fetched data from the web search engine.(2006)
 Built real-time TV caption alignment system, which was entitled Special Prize in the 3rd Beijing Challenge Cup Competition, and First Prize in the 9th National Challenge Cup Competition.(2004-2005)
 Participated in 2003, 2004, 2005 National 863 Evaluation on Mandarin Speech Recognition.(2003-2005)
 Built an oral Spoken English evaluation system using Verbal Information Verification technology.(2004)

Information Extraction

 Whisper Project (2008)
 Worked on automatic data labeling using Mechanic Turks service, currently working on selecting samples to be labeled, and maximize the t may boost the performance using multiple classifiers, so as to reduce the cost of obtaining labels.

Image Processing

 Worked on OCR of television captions, worked on caption frame boundary detection and caption region detection. (2004-2005)
