| Research Abstract |
This work focuses on the community identification problem in the social network and proposes a control theory approach to the problem. We utilize the influence network, where the dynamics of the social network is described as linear systems, and formulate the community identification problem as a linear hybrid system identification problem. This work proposes a matrix rank minimization and sparse optimization algorithm for the community identification. Numerical examples show the efficiency of the proposed algorithm.
