Zhi-Hua Zhou, Nanjing University, China Title: Ensemble and Semi-Supervised - Single or Combine

Abstract: Ensemble learning and semi-supervised learning are two different machine learning paradigms. They have almost the same goal, that is, to attain a strong generalization. Both paradigms have achieved great success during the past decade, however, they are almost separately developed since they have different cultures. Ensemble learning attempts to achieve strong generalization by using multiple learners; semi-supervised learning attempts to achieve strong generalization by exploiting unlabeled data. In this talk, we will give introduction to ensemble learning and semi-supervised learning, and discuss on why they can be helpful to each other.

Bio Sketch: Zhi-Hua Zhou received his B.Sc., M.Sc. and Ph.D. degrees in computer science from Nanjing University, China, in 1996, 1998 and 2000, respectively, all with the highest honor. He joined the Department of Computer Science & Technology of Nanjing University as an assistant professor in 2001, and at present he is Cheung Kong professor and founding director of the LAMDA Group.
