Yujia Li


I'm a Ph.D. student at University of Toronto. I work in the machine learning group and my advisor is Prof. Richard Zemel. My research now focuses on structured output learning, especially image labeling problems. Before coming to Toronto, I obtained my bachelor's degree from Tsinghua University, Beijing, China. I have worked as an intern Research and Development engineer at Baidu, Inc. (the largest search engine company in China) in the summer of 2011, and a Research Intern with the Speech Group at Microsoft Research Redmond in the summer of 2014.
