Annealing approximation in master-node network model

M. O. Hase, Anderson A. Ferreira, André C. R. Martins +1

This paper investigates absorbing-state phase transitions in opinion dynamics through a master-node network model analyzed using annealing approximation. We develop a theoretical f…

An Investigation into the Causal Mechanism of Political Opinion Dynamics: A Model of Hierarchical Coarse-Graining with Community-Bounded Social Influence

Valeria Widler, Barbara Kaminska, Andre C. R. Martins +1

The increasing polarization in democratic societies is an emergent outcome of political opinion dynamics. Yet, the fundamental mechanisms behind the formation of political opinions…

Memory CODA: introducing memory effects in the Continuous Opinions and Discrete Actions model

Andre C. R. Martins

The Continuous Opinions and Discrete Actions (CODA) model has been widely used to study the emergence of extremism in social networks. However, this standard model has been shown t…

Critical Exponents of Master-Node Network Model

Antonio Mihara, Anderson A. Ferreira, André C. R. Martins +1

The dynamics of competing opinions in social network play an important role in society, with many applications in diverse social contexts as consensus, elections, morality and so o…

Opinions and dark energy: A mechanism of long-range repulsion in a toy opinion particle model

André C. R. Martins

The concept of opinion particles can be introduced by studying time-continuous versions of Bayesian-inspired opinion dynamics methods. Here, we use opinion particles to further exp…

Agent mental models and Bayesian rules as a tool to create opinion dynamics models

Andre C. R. Martins

Traditional models of opinion dynamics provide a simple approach to understanding human behavior in basic social scenarios. However, when it comes to issues such as polarization an…
