| Research Abstract |
A social network can play an important role as a medium for the spread of various types of information, including innovation, hot topics and even malicious rumors. In this research, we have constructed predictable models for information diffusion phenomena in complex networks by exploiting a machine learning approach. Moreover, we have proposed and evaluated such a variety of applications of the models that present the methods of increasing and decreasing the information spread under given constraints, and analyzing behaviors of nodes in information propagation.
