Research on the Feature Selection Approach Based on IFDS and DPSO With Variable Thresholds in Complex Data Environments

open access: yesIEEE Access, 2020
Neighborhood rough model is widely used in feature selection with high dimension, fuzzy, continuous and discrete attributes, incomplete data and so on, and the application of neighborhood rough model depends on neighborhood threshold.

An Ensemble Classification Method for High-Dimensional Data Using Neighborhood Rough Set

open access: yesComplexity, 2021
Mining useful knowledge from high-dimensional data is a hot research topic. Efficient and effective sample classification and feature selection are challenging tasks due to high dimensionality and small sample size of microarray data.

A Neighborhood Rough Classification with Dempster-Shafer Evidence Theory

open access: yesNantong Daxue xuebao. Ziran kexue ban, 2021
In order to further improve the classification mechanism and the performance of neighborhood classifier, a Dempster-Shafer(D-S) evidence-driven neighborhood rough classification method is proposed.

Fundamental properties of fuzzy rough sets based on triangular norms and fuzzy implications: the properties characterized by fuzzy neighborhood and fuzzy topology

open access: yesComplex & Intelligent Systems, 2023
Fuzzy rough set models are useful tools for dealing with fuzzy and real-valued data. They have been used in many real-world applications. In this paper, we investigate the fuzzy rough set model based on triangular norms and fuzzy implications.

Multi-Label Attribute Reduction Based on Variable Precision Fuzzy Neighborhood Rough Set

open access: yesIEEE Access, 2020
Multi-label attribute reduction as a common dimensionality reduction technique has obtained widely research in recent years. Most existing multi-label attribute reduction methods adopt discretization to deal with mixed data and have strict requirements ...

Optimization of S-N curve fitting based on neighborhood rough set reduction with improved firefly algorithm

open access: yesFracture and Structural Integrity, 2023
S-N curve fatigue samples of titanium alloy welded joints have such a comparatively significant scatter, that results in the issue that the fatigue life prediction accuracy is not optimal.

The Challenge of Non-Technical Loss Detection using Artificial Intelligence: A Survey [PDF]

open access: yes, 2017
Detection of non-technical losses (NTL) which include electricity theft, faulty meters or billing errors has attracted increasing attention from researchers in electrical engineering and computer science. NTLs cause significant harm to the economy, as in
