Abstract

In this paper, we propose the Ensemble-Recursive-Rule eXtraction (E-Re-RX) algorithm, which is a rule extraction method from ensemble neural networks. We demonstrate that the use of ensemble neural networks produces higher recognition accuracy than individual neural networks and the extracted rules are more comprehensible. E-Re-RX algorithm is an effective rule extraction algorithm for dealing with data sets that mix discrete and continuous attributes. In this algorithm, primary rules are generated as well as secondary rules to handleonlythoseinstances that do not satisfy the primary rules, and then these rules are integrated. We show that this reduces the complexity of using multiple neural networks. This method achieves extremely high recognition rates, even with multiclass problems.
