Modeling Human-AI Team Decision Making
Wei Ye, Francesco Bullo, Noah Friedkin +1
AI and humans bring complementary skills to group deliberations. Modeling this group decision making is especially challenging when the deliberations include an element of risk and…
Structural Balance and Interpersonal Appraisals Dynamics: Beyond All-to-All and Two-Faction Networks
Wenjun Mei, Ge Chen, Noah E. Friedkin +1
Structural balance theory describes stable configurations of topologies of signed interpersonal appraisal networks. Existing models explaining the convergence of appraisal networks…
Expertise and confidence explain how social influence evolves along intellective tasks
Omid Askarisichani, Elizabeth Y. Huang, Abed K. Musaffar +3
Discovering the antecedents of individuals' influence in collaborative environments is an important, practical, and challenging problem. In this paper, we study interpersonal influ…
The 1995-2018 Global Evolution of the Network of Amicable and Hostile Relations Among Nation-States
Omid Askarisichania, Ambuj K. Singh, Francesco Bullo +1
We draw on the data collected by the Integrated Crisis Early Warning System on millions of international and regional public news stories, and this system's indicators of the orien…
Multi-group connectivity structures and their implications
Shadi Mohagheghi, Pushkarini Agharkar, Noah E. Friedkin +1
We investigate the implications of different forms of multi-group connectivity. Four multi-group connectivity modalities are considered: co-memberships, edge bundles, bridges, and…
Social power evolution in influence networks with stubborn individuals
Ye Tian, Peng Jia, Anahita Mirtabatabaei +3
This paper studies the evolution of social power in influence networks with stubborn individuals. Based on the Friedkin-Johnsen opinion dynamics and the reflected appraisal mechani…
Opinion Dynamics and Social Power Evolution: A Single-Timescale Model
Peng Jia, Noah E. Friedkin, Francesco Bullo
This paper studies the evolution of self-appraisal and social power, for a group of individuals who discuss and form opinions. We consider a modification of the recently proposed D…
Dynamic Social Balance and Convergent Appraisals via Homophily and Influence Mechanisms
Wenjun Mei, Pedro Cisneros-Velarde, Ge Chen +2
Social balance theory describes allowable and forbidden configurations of the topologies of signed directed social appraisal networks. In this paper, we propose two discrete-time d…
Opinion evolution in time-varying social influence networks with prejudiced agents
Anton V. Proskurnikov, Roberto Tempo, Ming Cao +1
Investigation of social influence dynamics requires mathematical models that are "simple" enough to admit rigorous analysis, and yet sufficiently "rich" to capture salient features…
Dynamic Models of Appraisal Networks Explaining Collective Learning
Wenjun Mei, Noah E. Friedkin, Kyle Lewis +1
This paper proposes models of learning process in teams of individuals who collectively execute a sequence of tasks and whose actions are determined by individual skill levels and…
Novel Multidimensional Models of Opinion Dynamics in Social Networks
Sergey E. Parsegov, Anton V. Proskurnikov, Roberto Tempo +1
Unlike many complex networks studied in the literature, social networks rarely exhibit unanimous behavior, or consensus. This requires a development of mathematical models that are…
Two Steps to Obfuscation
Noah E. Friedkin, Eugene C. Johnsen
This note addresses the historical antecedents of the 1998 PageRank measure of centrality. An identity relation links it to 1990-1991 models of Friedkin and Johnsen.
Complex Objects in the Polytopes of the Linear State-Space Process
Noah E. Friedkin
A simple object (one point in -dimensional space) is the resultant of the evolving matrix polynomial of walks in the irreducible aperiodic network structure of the first order D…
Generalization of the PageRank Model
Noah E. Friedkin
This paper develops a generalization of the PageRank model of page centralities in the global webgraph of hyperlinks. The webgraph of adjacencies is generalized to a valued directe…
Scale-free interpersonal influences on opinions in complex systems
Noah E. Friedkin
An important side effect of the evolution of the human brain is an increased capacity to form opinions in a very large domain of issues, which become points of aggressive interpers…
