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 ...

Fuzzy-rough set models and fuzzy-rough data reduction

open access: yesCroatian Operational Research Review, 2020
Rough set theory is a powerful tool to analysis the information systems. Fuzzy rough set is introduced as a fuzzy generalization of rough sets. This paper reviewed the most important contributions to the rough set theory, fuzzy rough set theory and their

An efficient feature selection based Bayesian and Rough set approach for intrusion detection

open access: yesApplied Soft Computing, 2020
The exponential growth of network size leads to increase attacks and intrusions. Detection of these attacks from the network has turned into a noteworthy issue of security. An intrusion detection system is an important approach to achieves high detection

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.

Confusion Matrices and Rough Set Data Analysis [PDF]

open access: yesJournal of Physics: Conference Series, 2019
A widespread approach in machine learning to evaluate the quality of a classifier is to cross – classify predicted and actual decision classes in a confusion matrix, also called error matrix.

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 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.
