An Algorithm for Computing All Rough Set Constructs for Dimensionality Reduction Open
In rough set theory, a construct is an attribute subset with the same ability to discern objects belonging to different classes as the whole set of attributes, while maintaining the similarity between objects belonging to the same class. A…

Learning-Based Dissimilarity for Clustering Categorical Data Open
Comparing data objects is at the heart of machine learning. For continuous data, object dissimilarity is usually taken to be object distance; however, for categorical data, there is no universal agreement, for categories can be ordered in …

An Algorithm for Computing Minimum-Length Irreducible Testors Open
In pattern recognition, the elimination of unnecessary and/or redundant attributes is known as feature selection. Irreducible testors have been used to perform this task. An objective of the Minimum Description Length Principle (MDL) appli…

On the Relation Between the Concepts of Irreducible Testor and Minimal Transversal Open
This paper aims at studying the relationship between two rather relevant theoretic fields such as Graph Theory and Testor Theory, deepening in the unexploited relation between the concepts of Minimal Transversal and Irreducible Testor. Fir…

Enhancing the Performance of YYC Algorithm Useful to Generate Irreducible Testors Open
In pattern recognition, irreducible testors have been used for feature selection. A number of exhaustive algorithms that find irreducible testors have been reported in the literature. One of the latest and more efficient algorithms reporte…
