Abstract

Summary We propose a standardized partition space that offers a unifying framework for the comparison of a wide variety of classification rules. Using standardized partition spaces, one can define measures for the performance of classifiers w.r.t. goodness concepts beyond the expected rate of correct classifications such that they are comparable for rules from so different techniques as support vector machines, neural networks, discriminant analysis, and many more. For classification problems with up to four classes, one can visualize partitions from classification rules that allow for a direct comparison of characteristic patterns of the rules. We use these visualizations to motivate measures for accuracy and non-resemblance in the sense of (Hand 1997), enhanced for non-probabilistic classifiers.
