Abstract

Three methods for attribute reduction in conjunction with Neural Networks, Naive Bayes, and k-Nearest Neighbor classifiers are investigated here when classifying a particularly challenging data set. The difficulty encountered with this data set is mainly due to the high dimensionality and to some inbalance between classes. As a result of this research, a subset of only 8 attributes (out of 34) is identified leading to a 92.7% classification accuracy. The confusion matrix analysis identifies class 7 as the one poorly learned across all combinations of attributes and classifiers. This information can be further used to upsample this underrepresented class or to investigate a classifier less sensitive to imbalance.
