    Xiaodong He is a Researcher in the Natural Language Processing Group.

    Background and Interests

    Xiaodong He received the BS degree from Tsinghua University (Beijing) in 1996, the MS degree from Chinese Academy of Sciences in 1999, and the PhD degree from University of Missouri - Columbia in 2003. His current research interests include statistical pattern recognition and machine learning, machine translation, speech recognition, and natural language processing. He is a senior member of IEEE and a member of ACL. He is a member of Sigma Xi.

    In 2006, he joined the Natural Language Processing (NLP) group of Microsoft Research (MSR), Redmond, WA, where he is currently working on various machine translation (MT) topics including system combination, word alignment, and model optimization. In the 2008 NIST Open MT Evaluation, he and colleagues submitted the MSR-NRC-SRI entry, which gave the best Chinese-to-English result in the Common-Data Track.

    Prior to joining NLP/MSR, he was with Microsoft Speech and Natural Language group from 2003 to 2006, where he engaged in a wide range of speech recognition research and development activities including large vocabulary discriminative training, confidence measure, and model adaptation. He has authored/coauthored more than 20 papers and one book in these areas. His work has been incorporated in a variety of Microsoft speech products.

    Special Issue in IEEE Journal of Selected Topics in Signal Processing

    we are organizing a Special Issue on Statistical Learning Methods for Speech and Language Processing which will be published in the IEEE Journal of Selected Topics in Signal Processing in 2010. Original and unpublished papers in the relevant areas are solicited.

    NIPS 2008 Workshop

    We orgnized the NIPS 2008 workshop Speech and Language: Learning-based Methods and Systems. It covers a variety of advanced topics in the Speech and Language Processing areas. More details can be found at NIPS08 WSL(a)
