Abstract
k-means is traditionally viewed as an unsupervised algorithm for the clustering of a heterogeneous population into a number of more homogeneous groups of objects. However, it is not necessarily guaranteed to group the same types (classes) of objects together. In such cases, some supervision is needed to partition objects which have the same class label into one cluster. This paper demonstrates how the popular k-means clustering algorithm can be profitably modified to be used as a classifier algorithm. The output field itself cannot be used in the clustering but it is used in developing a suitable metric defined on other fields. The proposed algorithm combines Simulated Annealing and the modified k-means algorithm. We also apply the proposed algorithm to real data sets, which result in improvements in confidence when compared to C4.5.
