Interval-Valued H-Fuzzy Sets [PDF]

International Journal of Fuzzy Logic and Intelligent Systems, 2010
We introduce the category IVSet(H) of interval-valued H-fuzzy sets and show that IVSet(H) satisfies all the conditions of a topological universe except the terminal separator property. And we study some relations among IVSet(H), ISet(H) and Set(H).

An Interval-Valued Divergence for Interval-Valued Fuzzy Sets [PDF]

, 2020
Characterizing the degree of similarity or difference between two sets is a very important topic, since it has many applications in different areas, including image processing or decision making. Several studies have been done about the comparison of fuzzy sets and its extensions, in particular for interval-valued fuzzy sets.

Specificity for interval-valued fuzzy sets [PDF]

International Journal of Computational Intelligence Systems, 2010
In this paper some axiomatic definitions about specificity for interval-valued fuzzy sets are proposed. Some examples of measures of specificity for interval-valued fuzzy sets are showed. It is also defined a extension of the notion of alpha cut for interval-valued fuzzy sets and a generalized similarity for intervalvalued fuzzy relations. An axiomatic

Interval Valued Intuitionistic Fuzzy β-Filters on β-Algebras

International Journal of Analysis and Applications, 2022
This study establishes the concept of interval valued intuitionistic fuzzy (InVInF) β-filters on β-algebras and a few of its related properties are investigated. Some compelling results of interval valued fuzzy β-filters have been examined.

REPRESENTABILITY IN INTERVAL-VALUED FUZZY SET THEORY [PDF]

International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2007
Interval-valued fuzzy set theory is an increasingly popular extension of fuzzy set theory where traditional [0,1]-valued membership degrees are replaced by intervals in [0,1] that approximate the (unknown) membership degrees. To construct suitable graded logical connectives in this extended setting, it is both natural and appropriate to "reuse ...

Distance-Based Knowledge Measure and Entropy for Interval-Valued Intuitionistic Fuzzy Sets

Mathematics, 2023
The knowledge measure or uncertainty measure for constructing interval-valued intuitionistic fuzzy sets has attracted much attention. However, many uncertainty measures are measured by the entropy of interval-valued intuitionistic fuzzy sets, which ...

Theoretical approaches of interval-valued fuzzy code and fuzzy soft code [PDF]

Journal of Fuzzy Extension and Applications
In this study, we attempted to demonstrate the interval-valued fuzzy code by extending the concept of an interval-valued fuzzy set. Further, we discussed the operations of the interval-valued fuzzy code. The interval-valued fuzzy soft code is introduced,
