The impact of noise and topology on opinion dynamics in social networks

Royal Society Open Science, 2021
We investigate the impact of noise and topology on opinion diversity in social networks. We do so by extending well-established models of opinion dynamics to a stochastic setting where agents are subject both to assimilative forces by their local social ...

Using a mixed opinion dynamics and innovation diffusion model to explore the 'best game no one played' phenomenon. [PDF]

PLoS ONE
Innovative products that receive favorable reviews but never catch on with consumers belong to a category known as the "best game no one played." We combined an adoption threshold model with an opinion dynamics model to examine reasons why certain high ...

Stable Boundaries of Opinion Dynamics in Heterogeneous Spatial Complex Networks [PDF]

Entropy
We investigate majority-vote opinion dynamics on Geometric Inhomogeneous Random Graphs (GIRGs), a powerful model for spatial complex networks. In contrast to classic coarsening dynamics, where a single opinion typically achieves global consensus, our ...

Analysis of Opinion Evolution Based on Hegselmann–Krause Model with Historical Opinion [PDF]

Entropy
In realistic social networks, individuals are influenced not only by current interactions, but also by recent historical opinions, prior experience, and external guidance.

An extended Hegselmann-Krause model incorporating agent heterogeneity and influence propagation. [PDF]

PLoS ONE
Traditional models of opinion dynamics provide a simplified framework for understanding human behavior in basic social scenarios. However, with the rise of complex communication patterns and heterogeneous social interactions in modern networks, more ...

Reinforcement learning-based optimal control for stochastic opinion dynamics [PDF]

Scientific Reports
This paper proposes a integrated framework for optimal control of opinion dynamics in social networks, addressing three progressively challenging scenarios: Model-based stochastic control, where agent interactions follow known probability distributions ...

Steering polarization toward consensus in signed majority-vote opinion models [PDF]

Scientific Reports
Signed social networks, which encode both positive and negative relationships, frequently constrain opinion dynamics, leading to sustained polarization.

Opinion dynamics in social networks under competition: the role of influencing factors in consensus-reaching

Royal Society Open Science, 2022
The rapid development of information technology and social media has provided easy access to the vast data on individual preferences and social interactions.

Dynamics of opinion forming in structurally balanced social networks. [PDF]

PLoS ONE, 2012
A structurally balanced social network is a social community that splits into two antagonistic factions (typical example being a two-party political system).

Mitigation of adversarial attacks on voter model dynamics by network heterogeneity

Journal of Physics: Complexity, 2023
Voter model dynamics in complex networks are vulnerable to adversarial attacks. In particular, the voting outcome can be inverted by adding extremely small perturbations that are strategically generated in social networks, even when one opinion is ...
