DYNAMICS OF NETWORKS AND OPINIONS
International Journal of Bifurcation and Chaos, 2007Social relations between people seldom follow regular lattice structures. In the Barabási–Albert model nodes link to the existing network structure with a probability proportional to the number of nodes previously attached. Here, we present an anthropologically motivated interpolation between Erdös–Rényi and Barabási–Albert rules, where people also ...

The problem of reaching an agreement in a multiagent system has been widely investigated. Opinion Dynamics is a similar problem where agents are assumed to interact in order to reach an agreement on their opinion. The key aspect of this formulation is that the time-varying network topology describing the interaction among agents is defined according ...

Opinion dynamics of skeptical agents
International Joint Conference on Autonomous Agents and Multiagent Systems, 2014How does skepticism affect opinion formation in networks? In many settings, agents exhibit skepticism in the presence of people whose beliefs radically different from their own, and they are reluctant to be persuaded by such individuals. We present a model of opinion dynamics where agents are receptive toward other agents that have similar opinions ...

State-dependent opinion dynamics
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014We study the simultaneous evolution of the opinion profile and network topology of a system of N agents. Based on the opinion profile at any given time, agents probabilistically decide which other agents to form links with. The probability of a link being formed with another agent depends on both similarity of their opinions and the popularity of that ...

Opinion Dynamics with Persistent Leaders
53rd IEEE Conference on Decision and Control, 2014This paper revisits the problem of agreement seeking in a social network under the influence of leaders. The persistence of the leader's effect on the opinions of other agents is characterized by the total weight that they place on the leader's information over time. If this weight is infinite, then the leader is called persistent. Our results describe

Opinion Dynamics of Elections in Twitter
2012 Eighth Latin American Web Congress, 2012In this work we conduct an empirical study of opinion time series created from Twitter data regarding the 2008 U.S. elections. The focus of our proposal is to establish whether a time series is appropriate or not for generating a reliable predictive model. We analyze time series obtained from Twitter messages related to the 2008 U.S.

A model of fuzzy opinion dynamics
2017 13th International Conference on Natural Computation, Fuzzy Systems and Knowledge Discovery (ICNC-FSKD), 2017Discrete 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
