Abstract

This paper explores classifier fusion problems where the task is selecting a subset of classifiers from a larger set with the goal to achieve optimal performance. To aid in the selection process we propose the use of several correlationbased diversity measures. We define measures that capture the correlation for n classifiers as opposed to pairs of classifiers only. We then suggest a sequence of steps in selecting classifiers. This method avoids the exhaustive evaluation of all classifier combinations which can become very large for larger sets of classifiers. We then report on observations made after applying that method to a data set from a real-world application. The classifier set chosen achieves close to optimal performance with a drastically reduced set of evaluation steps.
