Mathematical Analysis of Community Structure Detection in Complex Networks
Professor Xiang-Sun Zhang
Academy of Mathematics and Systems Science, CAS, Beijing, China.
Community Structure Detection is one of the popular research problems in the Complex Network study, which has closed relationship with Applied Mathematics and Computer Science. This talk introduces the basic definition of the community structure problem and surveys the development of methods finding the community structure in recent ten years, especially those using Optimization methodology such as heuristic models, stochastic optimization models and combinatoric models. From this presentation the author wants to tell that Applied Mathematics and Computer Science play very important roles in the Complex Network study.

Dr. Chen's research interests include social and information networks, networked game theory and economics, online learning, distributed computing, and fault tolerance. Dr. Chen, together with his colleagues, has initiated the study of scalable influence maximization, which has been widely cited and followed upon, and the proposed algorithms such as PMIA, LDAG, and IRIE have been widely used as the state-of-the-art in influence maximization research. Dr. Chen has also done a series of work on modeling complex influence diffusion dynamics (such as competitive diffusion) and their optimization tasks. Dr. Chen has coauthored a monograph "Information and Influence Propagation in Social Networks" in 2013, which systematically summarizes recent advances in computational social influence research.
Dr. Wei Chen won the prestigious William C. Carter Award in 2000 in the area of dependable computing, for his seminal dissertation work on the quality of service of failure detectors. Dr. Chen's co-authored paper on a novel game-theoretic approach for community detection in social networks won the best student paper award in ECML PKDD 2009. Dr. Chen regularly serves as program committee members in top international data mining and data management conferences, such as KDD, WSDM, SDM, SIGMOD, ICDE, WWW, etc. Dr. Chen is a member of the Big Data Task Force of Chinese Computer Federation.
Dr.Jie Tang is an Associate Professor with Department of Computer Science and Technology, Tsinghua University. Dr. Tang interests include social network analysis, data mining, and machine learning.
