Neutrosophic Soft Rough Graphs with Application

open access: yesAxioms, 2018
Neutrosophic sets (NSs) handle uncertain information while fuzzy sets (FSs) and intuitionistic fuzzy sets (IFs) fail to handle indeterminate information. Soft set theory, neutrosophic set theory, and rough set theory are different mathematical models for

Soft Interval-Valued Neutrosophic Rough Sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2015
In this paper, we first defined soft interval-valued neutrosophic rough sets(SIVN- rough sets for short) which combines interval valued neutrosophic soft set and rough sets and studied some of its basic properties.

A Study of Roughness in Modules of Fractions

open access: yesIEEE Access, 2019
The theory of rough sets is successfully applied in various algebraic systems (e.g. groups, rings, and modules). In this paper, the concept of roughness is introduced in modules of fractions with respect to its submodules.

Confidence Level Aggregation Operators Based on Intuitionistic Fuzzy Rough Sets With Application in Medical Diagnosis

open access: yesIEEE Access, 2023
In recent days, due to the complexities of different diseases of similar types, it becomes very difficult to diagnose an accurate type of disease, and so medical diagnosis becomes a difficult task for the experts working in health departments.

On Rough Sets and Hyperlattices

open access: yesRatio Mathematica, 2018
In this paper, we introduce the concepts of upper and lower rough hyper fuzzy ideals (filters) in a hyperlattice and their basic properties are discussed. Let $\theta$ be a hyper congruence relation on $L$. We show that if $\mu$ is a fuzzy subset of $L$,

A Deep Convolutional Neural Network With Fuzzy Rough Sets for FER

open access: yesIEEE Access, 2020
Existing facial emotion recognition methods do not have high accuracy and are not sufficient practical in real-time applications. We introduce type 2 fuzzy rough sets to develop a Type 2 Fuzzy Rough Convolutional Neural Network, as type 2 fuzzy rough ...

Rough Sets in Biomedical Informatics

open access: yesBiomath, 2013
The intent of this paper is to face the essentials of granular computing and in its major component -  the rough sets theory, introduced by Pawlak, since any rough set represents  an information granule.

Kernel Neighborhood Rough Sets Model and Its Application

open access: yesComplexity, 2018
Rough set theory has been successfully applied to many fields, such as data mining, pattern recognition, and machine learning. Kernel rough sets and neighborhood rough sets are two important models that differ in terms of granulation.
