报告简介:With a core-periphery structure of networks, core nodes are densely  interconnected, peripheral nodes are connected to core nodes to different  extents, and peripheral nodes are sparsely interconnected. Core-periphery  structure composed of a single core and periphery has been identified for  various networks. However, analogous to the observation that many empirical  networks are composed of densely interconnected groups of nodes, i.e.,  communities, a network may be better regarded as a collection of multiple cores  and peripheries. We propose a scalable algorithm to detect multiple  non-overlapping groups of core-periphery structure in a network. We illustrate  our algorithm using synthesized and empirical networks. For example, in a  world-wide airport network, we find three major groups of airports corresponding  to Europe, East Asia and the USA, and separation between international and  domestic subnetworks of airports in some single countries such as Thailand and  Philippines.

人物简介:Naoki Masuda received his PhD in 1998 from the University of Tokyo.  He worked as Lecturer and then Associate Professor at the University of Tokyo  between 2006 and 2014. He moved to University of Bristol, Department of  Engineering Mathematics as Senior Lecturer, March 2014. His main research  interests are network science and neuroimaging data analysis (using networks and  statistical physics). His other research interests include evolutionary games,  computational social science and collective behaviour.
