Direct and Indirect Influence on Likes in Social Media
Ivan Kozitsin, Anton V. Proskurnikov
The present study investigates direct and indirect social contagion mechanisms in an online social network environment. Using a large-scale dataset comprising approximately 290,000…
Continuous-Time Distributed Learning for Collective Wisdom Maximization
Luka Baković, Giacomo Como, Fabio Fagnani +2
Motivated by the well established idea that collective wisdom is greater than that of an individual, we propose a novel learning dynamics as a sort of companion to the Abelson mode…
Imitation and Heterogeneity Shape the Resilience of Community Currency Networks
Camilla Ancona, Dora Ricci, Carmela Bernardo +3
Community currency networks are made up of individuals and or companies that share some physical or social characteristics and engage in economic transactions using a virtual curre…
Wisdom of Crowds Through Myopic Self-Confidence Adaptation
Giacomo Como, Fabio Fagnani, Anton Proskurnikov
The wisdom of crowds is an umbrella term for phenomena suggesting that the collective judgment or decision of a large group can be more accurate than the individual judgments or de…
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…
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…
Coalescing Force of Group Pressure: Consensus in Nonlinear Opinion Dynamics
Iryna Zabarianska, Anton V. Proskurnikov
This work extends the recent opinion dynamics model from Cheng et al., emphasizing the role of group pressure in consensus formation. We generalize the findings to incorporate soci…
Opinion Dynamics with Set-Based Confidence: Convergence Criteria and Periodic Solutions
Iryna Zabarianska, Anton V. Proskurnikov
This paper introduces a new multidimensional extension of the Hegselmann-Krause (HK) opinion dynamics model, where opinion proximity is not determined by a norm or metric. Instead,…
Default Resilience and Worst-Case Effects in Financial Networks
Giuseppe Calafiore, Giulia Fracastoro, Anton Proskurnikov
In this paper we analyze the resilience of a network of banks to joint price fluctuations of the external assets in which they have shared exposures, and evaluate the worst-case ef…
