Text Box: Welcome to Lifeng SHANG’ Home Page

I am currently a 2-year Ph.D. student in the Department of Computer Science, University of Hong Kong (HKU), under the supervision of

Dr. K.P. Chan. I obtained my M.S. degree in Computational Intelligence Lab, University of Electronic Science and Technology of China

(UESTC) under the guidance of Prof. Zhang Yi. From Aug. 31, 2009, I start to visit Microsoft Research Asia (MSRA) as an intern.

Research Interests:

· Graphical Models, design specific GMs for recognition and vision problems

· Neural Networks, combining NNs to other models in which NNs serving as the representation function

· Information Retrieval, semantic analysis in social tagging systems, video duplicate detection
