I am currently a master student at Harbin Institute of Technology, affiliated with the research center for Social Computing and Information Retrieval (SCIR), supervised by Ting Liu. My research interests are in the areas of data mining on social networks, natural language processing and machine learning, with special interests in distributed representation learning and its applications. Prior to that, I received my Bachelor's degree in Computer Science and Technology at Harbin Institute of Technology, Harbin, China.
