Fuzzy Judgments and Fuzzy Sets

International Journal of Strategic Decision Sciences, 2010
Using fuzzy set theory has become attractive to many people. However, the many references cited here and in other works, little thought is given to why numbers should be made fuzzy before plunging into the necessary simulations to crank out numbers without giving reason or proof that it works to one’s advantage.

BOOLEAN FUZZY SETS

International Journal of Foundations of Computer Science, 2007
Extending the notion of context-free languages and equational sets, we use the approximation theory to define boolean subsets and boolean fuzzy subsets of an algebra. We establish some basic properties of boolean fuzzy sets.

ON ENTROPY OF FUZZY SETS

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2008
In this paper we deal with the entropy of fuzzy sets. We first review several defined entropies of fuzzy sets and then propose a new one. Some comparisons are made with some existing entropies to show the effectiveness of the proposed one.

On the fuzzy cardinality of a fuzzy set

International Journal of General Systems, 2006
We look at problem of determining the number of elements of a fuzzy set and its cardinality. It is noted that the simple adding of membership grades often does not lead to a satisfactory results. We investigate the use of a fuzzy subset of the non-negative integers to represent the cardinality of a fuzzy set. We prove a fundamental relationship between

Fuzzy soft sets as L -fuzzy sets

Journal of Intelligent & Fuzzy Systems, 2019
In this paper, it is shown that an L -fuzzy soft set on X with a set E of parameters can be regarded as an L X

Fuzzy rough sets are intuitionistic L-fuzzy sets

Fuzzy Sets and Systems, 1998
The concepts of intuitionistic \(L\)-fuzzy sets (IL-FS) [see \textit{K. Atanassov} and \textit{S. Stoeva}, ``Intuitionistic \(L\)-fuzzy sets'', in: R. Trappl (ed.), Cybernetics and systems research 2, 539-540 (1984; Zbl 0547.03030)], which are extensions of the IFSs [\textit{K. T. Atanassov}, ``Intuitionistic fuzzy sets'', Fuzzy Sets Syst.

Counting with Fuzzy Sets

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1986
The notion of fuzzy set cardinality is examined. Zadeh's suggested measure of fuzzy cardinality, the sigma-count, is adopted and shown to generalize classical counting measure. This allows many combinatorial structures and counting techniques to be fuzzified, and hence used in knowledge representation and pattern recognition models.
