| Outline of Final Research Achievements |
Spatio-temporal changes in the relationship between any two individuals in a population can be described by temporal networks, which is a series of graphs consisting of a set of nodes and links. In this study, incorporating a notion of inter-netowork distance, we proposed a new method for analyzing temporal networks and demonstrated its effectiveness in the prediction of temporal networks and structural analyses of various types of networks. We also investigated information diffusion on temporal networks and discuss the applicability of our method to its prediction and control.
