A model of fuzzy opinion dynamics

2017 13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD), 2017
Discrete and continuous opinion dynamics models have been widely studied in the contexts of social dynamics and group decision-making. However, the fuzziness of opinion is less well-concerned in existing contributions. Based on the fuzzy set theory, a fuzzy opinion dynamics model is proposed in this work. In our model, individual opinion is represented

Discrete-time opinion dynamics

2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011
We discuss the Hegselmann-Krause model for opinion dynamics in discrete-time for a symmetric confidence bound. We construct an adjoint dynamics and use it to define a Lyapunov comparison function that decreases along the trajectory of the opinion dynamics. Using the Lyapunov comparison function, we develop a novel upper bound on the convergence time of

Opinion Dynamics Under Opposition

SSRN Electronic Journal, 2013
We study a DeGroot-like opinion dynamics model in which agents may oppose other agents. As an underlying motivation, in our setup, agents want to adjust their opinions to match those of the agents they follow (their 'ingroup' or those they trust) and, in addition, they want to adjust their opinions to match the 'inverse' of those of the agents they ...
