Abstract

This paper presents a novel classification approach that integrates fuzzy class association rules and support vector machines. A fuzzy discretization technique is applied to transform the training set, particularly quantitative attributes, to a format appropriate for association rule mining. A hill-climbing procedure is adapted for automatic thresholds adjustment and fuzzy class association rules are mined accordingly. The compatibility between the generated rules and patterns is considered to construct a set of feature vectors, which are used to generate a classifier. The reported test results show that compatible rule-based feature vectors present a highly-qualified source of discrimination knowledge that can substantially impact the prediction power of the final classifier.
