A Minimal Dynamical Model for Incubation-Outbreak Transitions in Social Norm Diffusion
Run Wang, Leonardo Cianfanelli, Giacomo Como +1
In this paper, we introduce a minimal dynamical model for the diffusion of a new social norm, in which individuals transition among three states: non-supporters, silent supporters,…
Forgetting-Factor Regret for Online Zero-Sum Games
Yuhang Liu, Zi'ang Yan, Wenjun Mei +1
This paper studies dynamic equilibrium tracking in online two-player zero-sum games with time-varying convex-concave payoff functions. Existing regret metrics for online saddle-poi…
Modeling, Analysis, and Control of Continuous-Time Weighted-Median Opinion Dynamics
Yi Han, Julien M. Hendrickx, Ge Chen +1
Simple yet predictive mathematical models are essential for mechanistic understanding of opinion evolution in social groups. The weighted-median mechanism has recently been propose…
A Zeroth-order Resilient Algorithm for Distributed Online Optimization against Byzantine Edge Attacks
Yuhang Liu, Wenjun Mei
In this paper, we propose a zeroth-order resilient distributed online algorithm for networks under Byzantine edge attacks. We assume that both the edges attacked by Byzantine adver…
Meritocracy versus Matthew-effect: Two underlying network formation mechanisms of online social platforms
Yuchen Xu, Wenjun Mei, Ge Chen +1
With the rapid development of the internet industry, online social networks have come to play an increasingly significant role in everyday life. In recent years, content-based emer…
Convergence and consensus analysis of a class of best-response opinion dynamics
Yuchen Xu, Yi Han, Chuanzhe Zhang +2
Opinion dynamics aims to understand how individuals' opinions evolve through local interactions. Recently, opinion dynamics have been modeled as network games, where individuals up…
