Abstract:

To model the interdependent couplings of the multiple topics, we develop a set of rules for opinion updates of a group of agents. The rules are used to design or assign values to the elements of interdependent weighting matrices. The cooperative and anti-cooperative couplings are modeled in both the inverse-proportional and proportional feedbacks. The behaviors of cooperative opinion dynamics are analyzed using a Lyapunov candidate.  Various consensus properties are predicted according to the intra-agent network topology and interdependency topic topologies.

Bio: Hyo-Sung Ahn is a Professor at the School of Mechanical Engineering, Gwangju Institute of Science and Technology (GIST), Gwangju, Korea. He received the B.S. and M.S. degrees in astronomy from Yonsei University, Seoul, Korea, in 1998 and 2000, respectively, the M.S. degree in electrical engineering from the University of North Dakota, Grand Forks, in 2003, and the Ph.D. degree in electrical engineering from Utah State University, Logan, in 2006. Since July 2007, he has been with the School of Mechatronics and School of Mechanical Engineering, GIST. He was Dasan Distinguished Professor from 2013 to 2018 in GIST. Before joining GIST, he was a Senior Researcher with the Electronics and Telecommunications Research Institute, Daejeon, Korea. He is the author of the book Formation Control – Approaches for Distributed Agents, Springer, 2019. His research interests include distributed control, control of network systems, network localization, and learning control.
