I am a graduate student at the Department of Computer Sciences, University of Wisconsin-Madison, since August 2010. I am currently working on Machine Learning,advised by Professor Jerry Zhu.
I obtained my Bachelor's degree from the Department of Electronic Engineering, Tsinghua University,China ,on July 2010. I conducted research on Statistical Natural Language Processing and Machine Learning (particularly with graphical models) under the supervision of Professor Zhijian Ou.
I graduated in Dec,2013, and I will join in Twitter, anti-spam team since March,2014.
I like Machine Learning,both the theoretical study and application research. I worked on SAFE semi-supervised learning (SSL) algorithm, which is guaranteed to be no worse than supervised learning algorithm in theory. We conducted large scale experiments on diverse SSL algorithms and benchmark datasets in order to provide SSL tools for machine learning non-expert .
I am also interesed in social media mining, where practical social phenomenon are formulated into machine learning framework.
