Paper Abstract

In this paper, the Bayesian Data Reduction Algorithm is applied to a collection of medical diagnostic data sets found at the University of California at Irvine's Repository of Machine Learning databases. The algorithm works by finding the best performing quantization complexity of the feature vectors, and this makes it necessary to discretize all continuous valued features. Therefore, results are given by showing the quantization of the continuous valued features that yields best performance. Further, the Bayesian Data Reduction Algorithm is also compared to a conventional linear classifier, which does not discretize any feature values. In general, the Bayesian Data reduction Algorithm is shown to outperform the linear classifier by obtaining a lower probability of error, as averaged over all data sets.
