DISTINGUISHABILITY BASED WEIGHTED FEATURE SELECTION USING COLUMN WISE K NEIGHBORHOOD FOR THE CLASSIFICATION OF GENE MICROARRAY DATASET

Abstract

In data mining, much research is being carried out to discover the previously unknown, valid, novel, useful and understandable patterns in large databases. The patterns must be actionable so that they might be used for decision making to a variety of applications in healthcare. In this study, feature subset selection is an important area, where many approaches have been proposed. Hence, the authors chosen three existing feature selection algorithms analyzed their performance using the publicly available standard colon tumor dataset. The performance of the existing three methods evaluated and compared each method with DWFS-CKN under study.
