Feature Subset Selection Based on Variable Precision Neighborhood Rough Sets

open access: yesInternational Journal of Computational Intelligence Systems, 2021
Rough sets have been widely used in the fields of machine learning and feature selection. However, the classical rough sets have the problems of difficultly dealing with real-value data and weakly fault tolerance.

On Covering-Based Rough Intuitionistic Fuzzy Sets

open access: yesMathematics, 2022
Intuitionistic Fuzzy Sets (IFSs) and rough sets depending on covering are important theories for dealing with uncertainty and inexact problems. We think the neighborhood of an element is more realistic than any cluster in the processes of classification ...

Some New Covering-Based Multigranulation Fuzzy Rough Sets and Corresponding Application in Multicriteria Decision Making

open access: yesJournal of Mathematics, 2021
Multigranulation rough set theory is an important tool to deal with the problem of multicriteria information system. The notion of fuzzy β-neighborhood has been used to construct some covering-based multigranulation fuzzy rough set (CMFRS) models through

Extending Whitney's extension theorem: nonlinear function spaces [PDF]

open access: yes, 2020
We consider a global, nonlinear version of the Whitney extension problem for manifold-valued smooth functions on closed domains $C$, with non-smooth boundary, in possibly non-compact manifolds.

Feature Selection Combining Information Theory View and Algebraic View in the Neighborhood Decision System

open access: yesEntropy, 2021
Feature selection is one of the core contents of rough set theory and application. Since the reduction ability and classification performance of many feature selection algorithms based on rough set theory and its extensions are not ideal, this paper ...

Single-Valued Neutrosophic Covering-Based Rough Set Model Over Two Universes and Its Application in MCDM [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
This article aims to propose a new type of single-valued neutrosophic(SVN) covering-based rough sets over two universes by using Wang’s single-valued neutrosophic covering rough sets.

Covering Fuzzy Rough Sets via Variable Precision

open access: yesJournal of Mathematics, 2021
Lately, covering fuzzy rough sets via variable precision according to a fuzzy γ-neighborhood were established by Zhan et al. model. Also, Ma et al. gave the definition of complementary fuzzy γ-neighborhood with reflexivity.

Sensor data reduction with novel local neighborhood information granularity and rough set approach

open access: yesFrontiers in Physics, 2023
Data description and data reduction are important issues in sensors data acquisition and rough sets based models can be applied in sensors data acquisition. Data description by rough set theory relies on information granularity, approximation methods and
