Soft Covering Based Rough Sets and Their Application [PDF]

open access: yesThe Scientific World Journal, 2014
Soft rough sets which are a hybrid model combining rough sets with soft sets are defined by using soft rough approximation operators. Soft rough sets can be seen as a generalized rough set model based on soft sets.

An Attribute Reduction Method Using Neighborhood Entropy Measures in Neighborhood Rough Sets [PDF]

open access: yesEntropy, 2019
Attribute reduction as an important preprocessing step for data mining, and has become a hot research topic in rough set theory. Neighborhood rough set theory can overcome the shortcoming that classical rough set theory may lose some useful information ...

Some operations on rough bipolar interval neutrosophic sets [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
In this study we introduce the concept of rough bipolar interval neutrosophic sets which is a combination of rough sets and bipolar interval neutrosophi sets. Also, we define union, complement, intersection and some interesting properties of this set.

Approximations of interval neutrosophic hyperideals in semi-hyper-rings [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
This paper deals with the combination of rough sets and interval neutrosophic sets. We introduce the interval neutrosophic hyper-ideals in semi-hyper-rings. Also we study the rough interval neutrosophic hyper-ideals in semi-hyper-rings.

Cost-sensitive Multigranulation Approximation of Neighborhood Rough Fuzzy Sets [PDF]

open access: yesJisuanji kexue, 2023
Multigranulation neighborhood rough sets are a new data processing mode in the theory of neighborhood rough sets,in which the target concept can be characterized by upper/lower approximate boundaries of optimistic and pessimistic,respectively ...

Rough soft sets and rough soft groups [PDF]

open access: yesJournal of Hyperstructures, 2013
In this paper we discuss some basic properties of rough soft sets and hence we introduce the notion of rough soft group. Basic properties of rough soft group are presented and supported by some illustrative examples.

Agents and rough sets [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2014
Rough set theory gives approximation models of complex knowledge structure. Agents are not present in the definition of the rough sets. Now we will show that a set of conflicting agents or active set can be used to model inconsistent decision in rough ...

New Topological Approaches to Generalized Soft Rough Approximations with Medical Applications

open access: yesJournal of Mathematics, 2021
There are many approaches to deal with vagueness and ambiguity including soft sets and rough sets. Feng et al. initiated the concept of possible hybridization of soft sets and rough sets.

Label-based Approach for Dynamic Updating Approximations in Incomplete Fuzzy Probabilistic Rough Sets over Two Universes [PDF]

open access: yesJisuanji kexue, 2022
When the missing values are obtained in incomplete fuzzy probabilistic rough sets over two universes,the time efficiency of the traditional static algorithm for updating approximations in incomplete fuzzy probabilistic rough sets over two universes is ...
