Attribute number reduction process and nearest neighbor methods in machine learning

Abstract

Several nearest neighbor methods were applied to process of decision making to E522144 and modified bases, which are the collections of cases of melanocytic skin lesions. Modification of the bases consists in reducing the number of base attributes from 14 to 13, 4, 3, 2 and finally 1. The reduction process consists in concatenations of values of particular attributes. The influence of this process on the quality of decision making process is reported in the paper. © 2006 Springer.
