Kaisheng Yao

Kaisheng Yao is a researcher at Microsoft Research. He received his Ph.D. degree in Electrical Engineering in a joint program of Tsinghua University, China, and Hong Kong University of Science and Technology in 2000. From 2000 to 2002, he worked as an invited researcher at Advanced Telecommunication Research Lab in Japan. From 2002 to 2004, he was a post-doc researcher at Institute for Neural Computation at University of California at San Diego. From 2004 to 2008, he was with Texas Instruments. He joined Microsoft in 2008, first in a speech product group and later in Microsoft Research in 2013.

He has been active in both research and development areas including natural language understanding, speech recognition, machine learning and speech signal processing. He has published more than 50 papers in these areas and is the inventor/co-inventor of more than 20 granted/pending patents. At Microsoft, he has helped in shipping products such as smart watch gesture control, Bing query understanding, Xbox, and voice search. His current research and development interests are in the areas of deep learning using recurrent neural networks and its applications to natural language processing, document understanding, speech recognition and speech processing. He is a senior member of IEEE and a member of ACL.
