Modeling belief systems with scale-free networks
نویسندگان
چکیده
The evolution of belief systems has always been a focus of cognitive research. In this paper, we delineate a new model describing belief systems as a network of statements considered true. Testing the model with a small number of parameters enabled us to reproduce a variety of well-known mechanisms ranging from opinion changes to development of psychological problems. The self-organizing opinion structure showed a scale-free degree distribution. The novelty of our work lies in applying a convenient set of definitions allowing us to depict opinion network dynamics in a highly favorable way, which resulted in a scale-free belief network. As an additional benefit, we listed several conjectural consequences in a number of areas related to thinking and reasoning.

A Surface Water Evaporation Estimation Model Using Bayesian Belief Networks with an Application to the Persian Gulf
Evaporation phenomena is a effective climate component on water resources management and has special importance in agriculture. In this paper, Bayesian belief networks (BBNs) as a non-linear modeling technique provide an evaporation estimation method under uncertainty. As a case study, we estimated the surface water evaporation of the Persian Gulf and worked with a dataset of observations ...

متن کاملAn Overview of Distributed Belief Networks in Engineering Systems
This paper provides an overview of distributed belief networks and how they can model engineering systems. In extending the usual single-processor computational model to multiple processors, several interesting problems arise, which must be solved for the successful implementation of a distributed belief network. In keeping with the distributed computational model, no single processor has infor...
متن کاملGraphical Explanation in Belief Networks
Belief networks provide an important bridge between statistical modeling and expert systems. In this paper we present methods for visualizing probabilistic “evidence flows” in belief networks, thereby enabling belief networks to explain their behavior. Building on earlier research on explanation in expert systems, we present a hierarchy of explanations, ranging from simple colorings to detailed...
