Noisy continuous-opinion dynamics
We study the Deffuant et al. model for continuous–opinion dynamics under the influence of noise. In the original version of this model, individuals meet in random pairwise encounters after which they compromise or not depending of a confidence parameter. Free will is introduced in the form of noisy perturbations: individuals are given the opportunity to change their opinion, with a given probab...
متن کاملContinuous-Time Average-Preserving Opinion Dynamics with Opinion-Dependent Communications
We study a simple continuous-time multi-agent system related to Krause’s model ofopinion dynamics: each agent holds a real value, and this value is continuously attracted by everyother value differing from it by less than 1, with an intensity proportional to the difference.We prove convergence to a set of clusters, with the agents in each cluster sharing a commonvalue, and provi...
متن کاملModeling Education and Advertising with Opinion Dynamics
We present a modified Deffuant-Weisbuch opinion dynamics model that integrates the influence of media campaigns on opinion. Media campaigns promote messages intended to inform and influence the opinions of the targeted audiences through factual and emotional appeals. Media campaigns take many forms: brand-specific advertisements, promotions, and sponsorships, political, religious, or social mes...
متن کاملModeling Opinion Dynamics in Diffusion Networks
Social media and social networking sites have become a global pinboard for exposition and discussion of news, topics, and ideas, where social media users often form their opinion about a particular topic by learning information about it from her peers. In this context, whenever a user posts a message about a topic, we observe a noisy estimate of her current opinion about it, however, the influe...
متن کاملDynamical affinity in opinion dynamics modeling.
We propose here a model to simulate the process of opinion formation, which accounts for the mutual affinity between interacting agents. Opinion and affinity evolve self-consistently, manifesting a highly nontrivial interplay. A continuous transition is found between single and multiple opinion states. Fractal dimension and signature of critical behavior are also reported. A rich phenomenology ...
