Attribute Reduction of Variable Precision Fuzzy Rough Set Based on Misclassification Cost [PDF]

open access: yesJisuanji kexue, 2022
Attribute reduction is a hot research issue in rough set.In this paper, how to reduce redundant attributes without increasing the misclassification cost is studied.Firstly, the minimum misclassification degree of variable precision fuzzy rough sets is ...

Autonomous clustering using rough set theory [PDF]

open access: yes, 2008
This paper proposes a clustering technique that minimises the need for subjective human intervention and is based on elements of rough set theory. The proposed algorithm is unified in its approach to clustering and makes use of both local and global ...

Fermatean neutrosophic rough set [PDF]

open access: yesComputational Algorithms and Numerical Dimensions
In order to balance uncertainty, a reasonable approximation of a crisp set that yields lower as well as upper approximations of the set is made. Here, first, a special class of Fermatean Neutrosophic Set is devised by associating the Neutrosophic Set ...

The Upper and Lower Approximations in Rough Subgroupoid of a Groupoid

open access: yesMoroccan Journal of Pure and Applied Analysis, 2018
In this article, we introduce the concept of rough subgroupoid of a groupoid as a generalization of a rough subgroup and give some features about the lower and the upper approximations in a groupoid [1]. We give some of the characterization of them.

The use of rough rules in the selection of topographic objects for generalizing geographical information

open access: yesPolish Cartographical Review, 2020
Selection is a key element of the cartographic generalisation process, often being its first stage. On the other hand it is a component of other generalisation operators, such as simplification.

Rough Standard Neutrosophic Sets: An Application on Standard Neutrosophic Information Systems [PDF]

open access: yesNeutrosophic Sets and Systems, 2016
A rough fuzzy set is the result of the approximation of a fuzzy set with respect to a crisp approximation space. It is a mathematical tool for the knowledge discovery in the fuzzy information systems.

Rough analysis in lattices [PDF]

open access: yes, 1991
An outline of an algebraie generalization of the rough set theory is presented in the paper. It is shown that the majority of the basic concepts of this theory has an immediate algebraic generalization, and that some rough set facts are true in general ...

Rough Neutrosophic Sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2014
Both neutrosophic sets theory and rough sets theory are emerging as powerful tool for managing uncertainty, indeterminate, incomplete and imprecise information.

Pythagorean fuzzy soft rough sets and their applications in decision-making

open access: yesJournal of Taibah University for Science, 2020
This paper aims to originate two new notions that are soft rough Pythagorean fuzzy set and Pythagorean fuzzy soft rough set, and investigate some important properties of soft rough Pythagorean fuzzy set and Pythagorean fuzzy soft rough set in detail ...

Decision-Theoretic Rough Set: A Fusion Strategy

open access: yesIEEE Access, 2020
Decision-theoretic rough set is a popular topic. However, such single-granulation rough set model is not able to handle complex information well, such as multi-source, multi-scale and high dimensions data.
