Neighbourhood systems based attribute reduction in formal decision contexts

open access: yesCAAI Transactions on Intelligence Technology, 2019
Attribute reduction of formal decision context mainly uses the relationship between two concept lattices generated by the condition and decision attributes to remove redundant condition attributes.

Lower Approximation Reduction Based on Discernibility Information Tree in Inconsistent Ordered Decision Information Systems

open access: yes, 2018
Attribute reduction is an important topic in the research of rough set theory, and it has been widely used in many aspects. Reduction based on an identifiable matrix is a common method, but a lot of space is occupied by repetitive and redundant ...

An Improved Rough Clustering Using Discernibility Based Initial Seed Computation [PDF]

open access: yes, 2010
In this paper, we present the discernibility approach for an initial seed computation of Rough K-Means (RKM). We propose the use of the discernibility initial seed computation (ISC) for RKM.

Attribute reduction based on maximal rules in decision formal context [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2014
One of the key issues in the theory of concept lattices is to extract the useful rules from the decision formal context. The maximal rules implicate the others, thus people are interested in them.

Adjustable soft discernibility matrix based on picture fuzzy soft sets and its applications in decision making

open access: yes, 2015
In this work, we first define picture fuzzy soft sets and study some of their relevant properties, especially, a sufficient and necessary condition is presented to ensure that the dual laws are true in picture fuzzy soft theory.

Identity and Discernibility in Philosophy and Logic

open access: yes, 2012
Questions about the relation between identity and discernibility are important both in philosophy and in model theory. We show how a philosophical question about identity and discernibility can be ‘factorized’ into a philosophical question about the ...

ATTRIBUTE VALUE PAIRS BASED ON DISCERNIBILITY MATRIX FOR OUTLIERS DETECTION

open access: yes, 2022
Outlier mining is one important task in data mining and it has always been receiving attention from many researchers. The detection of outliers is found useful in many real applications like fraud detection and network intrusion.

Generalized Discernibility Function Based Attribute Reduction in Incomplete Decision Systems [PDF]

open access: yes, 2013
A rough set approach for attribute reduction is an important research subject in data mining and machine learning. However, most attribute reduction methods are performed on a complete decision system table.

A Variable Precision Attribute Reduction Approach in Multilabel Decision Tables

open access: yesThe Scientific World Journal, 2014
Owing to the high dimensionality of multilabel data, feature selection in multilabel learning will be necessary in order to reduce the redundant features and improve the performance of multilabel classification.
