QCIS Seminar: A New Challenge of Traditional Information Processing in the Web Age - Prof Bo Zhang, Tsinghua Univesity, China

Presenter: Prof Bo Zhang, Tsinghua University, China (invited by Prof Mingsheng Ying)

Abstract:  In the web era, we are confronted with a huge amount of raw data and a tremendous change in man-machine interaction modes. We have to deal with the content (semantics) of data rather than their form alone. Traditional information processing approaches face a new challenge because they are based on content independent assumptions so that they cannot deal with the semantic aspects of information. But humans can handle such a problem easily. So a new information processing strategy is needed that correlates with the content of information by learning mechanisms from human beings. Therefore, we need:

            1.         a set of robust detectors to detect semantically meaningful features such as boundaries, shapes, and the like in images, words, sentences, etc. in text, and

            2.         a set of methods that can effectively analyze and exploit the information structures that encode the content of information.

During the past 40 years probability theory has made great progress. It has provided a set of mathematical tools for representing and analyzing information structures. In the talk we will discuss what difficulties we face, what we can do, and how we should do it in content-related information processingg.

Short Bio: Prof Bo Zhang is a Professor at the Dept of  Computer Science and Technology at Tsinghua University. He is a Fellow of the Chinese Academy of Sciences. He graduated from the Dept of Automatic Control at Tsinghua Uni in 1958 and has been a Faculty member since then. In 1980-2 he visited the University of Illinois at Urbana-Champaign, USA as a scholar. Hamburg University awarded him an Honorary Doctor of Natural Sciences in 2011. He is a member of the Technical Advisory Board for Microsoft Research Asia.

Prof Zhang is engaged in research on artificial intelligence, artificial neural networks, and machine learning. He is also researching technology that applies theories for AI, AI neural networks and machine learning into pattern recognition, knowledge engineering, and robotics. He has published over 200 papers and five monographs (chapters) in these fields. His monograph, "Theory and Applications of Problem Solving" in Chinese/English won the special class prize for excelllent academic monograhps by the College and University Press, and was awarded by the State Educational Commission. He won the won the ICL European Artificial Intelligence prize for his academic achievements. He has taken part in strengthening the State Key Lab for Intelligent Technology and Systems, and served as Director of the Lab from 1990 to 1996.

Prof Zhang recently founded a research group for cognitive computation and multimedia information processing. The group has achieved important results in machine learning, image and video analysis and retrieval.
