In this paper, we compare the inference capabilities of three different types of Fuzzy Cognitive Maps. A Fuzzy Cognitive Map is a Recurrent Artificial Neural Network that creates models as collections of concepts/neurons and the various causal relations that exist between these concepts/neurons. The three different types of Fuzzy Cognitive Maps that we study are the Binary, the Trivalent and th...

Cognitive science is an interdisciplinary enterprise. This review highlights how the philosophical notion of a 'sortal'--a concept that provides principles of individuation and principles of identity - has been introduced into cognitive developmental psychology. Although the notion 'sortal' originated in metaphysics, importing it into the cognitive sciences has bridged a gap between philosophic...

This paper presents a triangular model of concept structure and four developmental levels of physical concepts: primitive, empirical, exact, and formal. The model is built upon Vygotsky’s concept theory and derived from the semantic modeling of concepts. The basic components of the model are: core C, meaning M, meaning layers M1, M2, M3, sense S, and their relationships. This model also disting...

The article attempts to present a thorough analyses of concept from the position two linguistic perspectives. notion is shared property and means representation for both linguoculturology cognitive linguistics. viewed as mental representation, fragments human life experience, abstract rational categories shaped in individual’s world picture. Having numerous ways through language units language,...

Fuzzy semantics comprehension and fuzzy inference are two of the central abilities of human brains that play a crucial role in thinking, perception, and problem solving. A formal methodology for rigorously describing and manipulating fuzzy semantics and fuzzy concepts is sought for bridging the gap between humans and cognitive fuzzy systems. A mathematical model of fuzzy concepts is created bas...

Experiments in this article test the hypothesis that formal direction models used in artificial intelligence correspond to intuitive direction concepts of humans. Cognitively adequate formal models of spatial relations are important for information retrieval tasks, cognitive robotics, and multiple spatial reasoning applications. We detail two experiments using two objects (airplanes) systematic...

In modern societies, spectrum bands become very expensive and highly requested resources. Many applications based on wireless communications require smart collaboration and wise sharing of available resources. To achieve this goal, concepts of cognitive radio have been recently formulated. Even though, these systems are newly proposed, many researchers are becoming enthusiastically involved in ...
