School of Computer Science
Carnegie Mellon University
Roger Hsiao received his M.S. degree from the Language Technologies Institute (LTI) of Carnegie Mellon University in 2007, and his B. Eng. and M. Phil. degree in Computer Science from the Hong Kong University of Science and Technology (HKUST) in 2002 and 2004. From August 2007, He became a PhD candidate of LTI under the supervision of Prof Tanja Schultz. His research interests include speech recognition, machine learning and pattern recognition. He received a honorable mention award in 2009 LTI Student Research Symposium. In 2002, He represented HKUST in the ACM International Collegiate Programming Contest and became a coach of HKUST programming team in 2003. He received a merit award in the 5th ACM Postgraduate Research Day organized by ACM Hong Kong Chapter in 2004 for his research on discriminative training.
