MERBIS - A Self-Adaptive Multi-Objective Evolutionary Rule Base Induction System

Supervised classification is a particular data-mining task that forms part of the knowledge discovery process. Its objectives are to extract accurate, comprehensible and interesting knowledge form data. However, many existing supervised classification approaches only focus on one of these objectives. This paper introduces a Multi-Objective Evolutionary Rule Base Induction System called MERBIS that is capable of producing trade-off solutions with regard to the accuracy and comprehensibility objectives. We utilise a superior accuracy measure, problem-tailored genetic operators and a self-adaptive mechanism that reduces the number of parameters. We compare MERBIS with several existing approaches for supervised classification on a number of benchmark data sets and show that it performs comparable while producing more comprehensible classi-
