作者: OF Mikhal' 摘要: The aim of this study was to assess the impact of isolation on forest bird communities in agricultural landscapes in The Netherlands. We studied the avifauna of 235 small (0.1-39 ha) woodlots composed of mature deciduous trees in 1984-1985. These woodlots were ...
Set TheoryThesauriThe object of this paper is to present a mathematical model of information retrieval system based on the concept of fuzzy thesaurus. For this purpose the mathematical methods of A. Zadeh's theory of fuzzy sets have been used. The application of the theory of fuzzy sets to ...
A general class of consensus measures of fuzzy sets is introduced in this paper. It is shown that, while the consensus measures are valuations but neither isotone nor antitone with respect to the lattice structure induced by the pointwise maximum and minimum operations to the set of all the ...
Regarding optimization, the initial fuzzy set selection was assumed to be of regular shape (sinusoidal, trapezoidal or triangular). An irregular shape may be required by some systems. Hence, a genetic algorithm was proposed as a methodology to optimize the performance of fuzzy systems by mutating ...
The Gaussian fuzzy membership function depends on two parameters, the center and the width of a fuzzy set. Gaussian FMFs are popular for expressing symmetrical and smooth fuzzy sets. The Gaussian FMF can be obtained using the unity-based normalization, or the rescaling of the PDF to the range...
In this chapter, based on the original idea of Wille of formal concept analysis and the AFS (Axiomatic Fuzzy Set) theory, we presents a rigorous mathematical treatment of fuzzy formal concept analysis referred to as an AFS Formal Concept Analysis (AFSFCA). It naturally augments the existing for...
It is obvious that the construction of such knowledge bases requires a large amount of human effort. In this paper, an intelligent fuzzy information retrieval system with an automatically constructed knowledge base is presented; the knowledge base is represented by a multi-relationship fuzzy concept ...
