Rough sets models inspired by supra-topology structures. [PDF]

open access: yesArtif Intell Rev, 2023
Our aim of writing this manuscript is to found novel rough-approximation operators inspired by an abstract structure called “supra-topology”. This approach is more relaxed than topological ones and extends the scope of applications because an ...

Rough sets

open access: yesCommunications of the ACM, 1995
Rough set theory, introduced by Zdzislaw Pawlak in the early 1980s [11, 12], is a new mathematical tool to deal with vagueness and uncertainty. This approach seems to be of fundamental importance to artificial intelligence (AI) and cognitive sciences, especially in the areas of machine learning, knowledge acquisition, decision analysis, knowledge ...

Rough sets: past, present, and future. [PDF]

open access: yesNat Comput, 2018
Introduction of rough sets by Professor Zdzisław Pawlak has completed 35 years. The theory has already attracted the attention of many researchers and practitioners, who have contributed essentially to its development, from all over the world.

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.

soft sets, soft rough sets, soft pre-rough sets, information system, decision making

open access: yesAIMS Mathematics, 2023
For any real $ \beta $ let $ H^2_\beta $ be the Hardy-Sobolev space on the unit disc $ {\mathbb D} $. $ H^2_\beta $ is a reproducing kernel Hilbert space and its reproducing kernel is bounded when $ \beta > 1/2 $.

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.

Interval neutrosophic covering rough sets based on neighborhoods

open access: yesAIMS Mathematics, 2021
Covering rough set is a classical generalization of rough set. As covering rough set is a mathematical tool to deal with incomplete and incomplete data, it has been widely used in various fields. The aim of this paper is to extend the covering rough sets
