Hyperedge approximation for stochastic processes on higher-order networks
Anzhi Sheng, Alex McAvoy, Ye Tian +3
Graphs are a standard framework for describing dynamical processes shaped by pairwise interactions among agents. But many systems involve interactions in groups of three or more ag…
How social influence affects the wisdom of crowds in influence networks
Ye Tian, Long Wang, Francesco Bullo
A long-standing debate is whether social influence improves the collective wisdom of a crowd or undermines it. This paper addresses this question based on a naive learning setting…
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 in social networks with stubborn agents: an issue-based perspective
