Education I am a graduate student in the Department of Computer Science and Engineering at Washington University in St Louis since 2006. I received my M.S. degree in Control Science from Tsinghua University in 2006 and a BS degree in Electrical Engineering from Zhejiang University in 2003. Course Study Advanced Algorithm, Data Mining, Programming Langrage and Systems, Computational Geometry, Formal Langrage and Automata, Introduction to Artificial Intelligence, Computer Architecture and Systems. Research Interests My primary research interests are machine learning, pattern recognition, data mining and multi-media information retrieval. In particular, I am interested in the following areas: Learning to rank Semi-supervised Learning Manifold Learning Text Mining Content-based Multi-media Retrieval Papers Yunpeng Xu, Xuefeng Zhou, Weixiong Zhang.
