Rule Generation Based on Novel Kernel Intuitionistic Fuzzy Rough Set Model

open access: yesIEEE Access, 2018
This paper develops a novel kernel intuitionistic fuzzy rough set (KIFRS) model as a hybrid model to improve the effects of rule generation based on rough sets.

The use of rough rules in the selection of topographic objects for generalizing geographical information

open access: yesPolish Cartographical Review, 2020
Selection is a key element of the cartographic generalisation process, often being its first stage. On the other hand it is a component of other generalisation operators, such as simplification.

Enabling decision trend analysis with interactive scatter plot matrices visualization [PDF]

open access: yes, 2016
© 2015 Elsevier Ltd. This paper presents a new interactive scatter plot visualization for multi-dimensional data analysis. We apply Rough Set Theory (RST) to reduce the visual complexity through dimensionality reduction.

Rough-Set-Theory-Based Classification with Optimized k-Means Discretization

open access: yesTechnologies, 2022
The discretization of continuous attributes in a dataset is an essential step before the Rough-Set-Theory (RST)-based classification process is applied. There are many methods for discretization, but not many of them have linked the RST instruments from ...

Hepatitis B Disease Diagnosis Using Rough Set

open access: yesCommunications, 2013
This paper describes processing of the medical data by means of the prediction system based on Rough Set Theory (RST). The Rough Sets proved to be very useful for the analysis of the decision problems concerning objects described in a data table by a set

Autonomous clustering using rough set theory [PDF]

open access: yes, 2008
This paper proposes a clustering technique that minimises the need for subjective human intervention and is based on elements of rough set theory. The proposed algorithm is unified in its approach to clustering and makes use of both local and global ...

New Measures of Uncertainty for Interval-Valued Data With Application to Attribute Reduction

open access: yesIEEE Access, 2022
Uncertainty measurement (UM) gives a brand-new perspective on attribute reduction in an information system (IS). Interval-valued data is a kind of very vital data in rough set theory (RST).

Attribute Reduction Method Based on Generalized Grey Relational Analysis and Decision-Making Trial and Evaluation Laboratory

open access: yesIEEE Access, 2020
Attribute reduction is a challenging issue in intelligent manufacturing. Existing methods are mainly based on rough set theory (RST) focusing on symbolic and discrete values.
