On a Closed-Loop Controller for the Coevolutionary Model of Actions and Opinions via Broadcasting Information
Roberta Raineri, Mengbin Ye, Lorenzo Zino
We deal with controlling a complex social network in which agents have actions and opinions that coevolve, mutually influencing one another. We consider an input consisting in broa…
On Leadership Emergence in Opinion Dynamics on Social Networks
Martina Alutto, Lorenzo Zino, Karl H. Johansson +1
Leadership in social groups emerges dynamically through interaction and opinion exchange. Empirical evidence indicates that individuals expressing strong opinions tend to gain infl…
Modelling the coevolution of opinion dynamics and decision making in social dilemmas
Ella C. Davidson, Lorenzo Zino, Ming Cao +1
This paper proposes a mathematical model for the coevolution of actions and opinions for a population facing a social dilemma. In particular, we assume each person participates in…
On a Co-evolving Opinion-Leadership Model in Social Networks
Martina Alutto, Lorenzo Zino, Karl H. Johansson +1
Leadership in social groups is often a dynamic characteristic that emerges from interactions and opinion exchange. Empirical evidence suggests that individuals with strong opinions…
Tackling Heterogeneity in Federated Learning via Variance-Reduced Boltzmann Sampling within Homogeneous Social Coalitions
Alessandro Licciardi, Roberta Raineri, Anton Proskurnikov +2
Federated Learning (FL) enables privacy-preserving collaborative model training, but its effectiveness is often limited by client data heterogeneity. We introduce a client-selectio…
Controlling a Social Network of Individuals with Coevolving Actions and Opinions
Roberta Raineri, Mengbin Ye, Lorenzo Zino
In this paper, we consider a population of individuals who have actions and opinions, which coevolve, mutually influencing one another on a complex network structure. In particular…
FJ-MM: The Friedkin-Johnsen Opinion Dynamics Model with Memory and Higher-Order Neighbors
Roberta Raineri, Lorenzo Zino, Anton Proskurnikov
The Friedkin-Johnsen (FJ) model has been extensively explored and validated, spanning applications in social science, systems and control, game theory, and algorithmic research. In…
On stochastic imitation dynamics in large-scale networks
Lorenzo Zino, Giacomo Como, Fabio Fagnani
We consider a broad class of stochastic imitation dynamics over networks, encompassing several well known learning models such as the replicator dynamics. In the considered models,…
On imitation dynamics in potential population games
Lorenzo Zino, Giacomo Como, Fabio Fagnani
Imitation dynamics for population games are studied and their asymptotic properties analyzed. In the considered class of imitation dynamics - that encompass the replicator equation…
Diffusion of innovation in large scale graphs
Fabio Fagnani, Lorenzo Zino
Will a new smartphone application diffuse deeply in the population or will it sink into oblivion soon? To predict this, we argue that common models of spread of innovations based o…
