Social Networks Analysis: Consensus or Disagreement?

Back
Abstract:
The recent years have shown substantial activities towards the study of dynamic social networks analysis, which were opened up by rapid progresses in complex systems and networks. A closer examination of these systems has revealed some common principles regarding coordination and self-organization, including consensus protocols for distributed decision making. This discovery attracted the attention of many research communities to models of social groups evolution, which often exhibit rich and non-trivial dynamics, and sometime show persistent disagreement or other irregular behaviors.

The number of dynamic models which describe social group dynamics is currently growing. Their properties are not yet deeply investigated from the systems and control-theoretic viewpoint. In particular, some basic problems concerning identification, stability, convergence and resilience still remain unsolved. Furthermore, how useful are these models to describe the behavior of large groups in real social networks is still a widely open question. This lecture will address these issues, and also provide an analysis on belief system dynamics under logic constraints.

Biographical Sketch:
Roberto Tempo is currently a Director of Research of Systems and Computer Engineering at the institute IEIIT, National Research Council (CNR), Politecnico di Torino, Italy. His research activities are mainly focused on the analysis and design of complex networked systems subject to uncertainty, and various related applications within information technology which currently include opinion dynamics in social networks, the PageRank computation in the Google search engine and distributed localization of wireless sensor networks. On these topics, he has published more than 200 research papers in international journals, books and conferences. He is also a co-author of the book "Randomized Algorithms for Analysis and Control of Uncertain Systems," Springer-Verlag, London, published in two editions in 2005 and 2013.
Dr. Tempo is a Fellow of the IEEE and a Fellow of the IFAC. He is a recipient of the "IEEE Control Systems Magazine Outstanding Paper Award", of the "Automatica Outstanding Paper Prize Award" and of the "Distinguished Member Award" from the IEEE Control Systems Society. He is a Corresponding Member of the Academy of Sciences, Institute of Bologna, Italy, Class Engineering Sciences.
In 2010 Dr. Tempo was President of the IEEE Control Systems Society. He is currently serving as Editor-in-Chief of Automatica. He has been a Senior Editor of the IEEE Transactions on Automatic Control in 2011-2014 and Editor for Technical Notes and Correspondence of the same journal in 2005-2009. He is a member of the Advisory Board of Systems & Control: Foundations & Applications, Birkhauser. He was General Co-Chair of the IEEE Conference on Decision and Control, Florence, Italy, 2013 and Program Chair of the first joint IEEE Conference on Decision and Control and European Control Conference, Seville, Spain, 2005.
