Polarized Ukraine 2014: opinion and territorial split demonstrated with the bounded confidence XY model, parametrized by Twitter data [PDF]
Royal Society Open Science, 2018 Multiple countries have recently experienced extreme political polarization, which, in some cases, led to escalation of hate crime, violence and political instability.

Weighted Beta Regression for Modeling Bounded Data [PDF]
EntropyA two-parameter weighted beta distribution is introduced for modeling bounded data, which has many similarities to the beta distribution. We propose a class of regression models where the response is weighted beta distributed and the two shape parameters

Evacuation by leader-follower model with bounded confidence and predictive mechanisms [PDF]
Archives of Control Sciences, 2021 This paper studies an evacuation problem described by a leader-follower model with bounded confidence under predictive mechanisms. We design a control strategy in such a way that agents are guided by a leader, which follows the evacuation path.

Exploring the formation dynamics of affective polarization by considering coupled feedback
Frontiers in Physics, 2023 Polarization issues are generally subject to ideological and affective polarization. Particularly, affective polarization generally accelerates the polarization process.

An opinion dynamics model based on affinity and social noise
Frontiers in Physics, 2022 Most previous works have studied the evolution of opinions based on the Hegselmann–Krause model, the Deffuant–Weisbuch model, and the Sznajd model. However, the influence of social influence on opinions is discussed less.

Computers, 2023 The opinion dynamics literature argues that the way people perceive social influence depends not only on the opinions of interacting individuals, but also on the individuals’ non-opinion characteristics, such as age, education, gender, or place of ...

When network bridges foster consensus. Bounded confidence models in networked societies
Physical Review Research, 2021 In this work we present results to the problem of the Hegselmann-Krause dynamics in networks obtained by an extensive study of the behavior of the standard order parameter sensitive to the onset of consensus: the normalized size of the giant cluster ...

Bounded-confidence model of opinion dynamics with heterogeneous node-activity levels
Physical Review Research, 2023 Agent-based models of opinion dynamics allow one to examine the spread of opinions between entities and to study phenomena such as consensus, polarization, and fragmentation.

Bounded confidence model on growing populations [PDF]
International audienceThis paper studies the bounded confidence model on growing fully-mixed populations. In this model, in addition to the usual opinion clusters, significant secondary clusters of smaller size appear systematically, while those ...

Evolution of Bounded Confidence Opinion in Social Networks
Discrete Dynamics in Nature and Society, 2017 We investigate opinion dynamics as a stochastic process in social networks. We introduce the stubborn agent in order to determine the impact of network structure on the emergence of consensus.
