Abstract

When a Multiple Classifier System is employed, one of the most popular methods to accomplish the classifier fusion is the simple majority voting. However, when the performance of the ensemble members is not uniform, the efficiency of this type of voting is affected negatively. In this paper, a comparison between simple and weighted voting (both dynamic and static) is presented. New weighting methods, mainly in the direction of the dynamic approach, are also introduced. Experimental results with several real-problem data sets demonstrate the advantages of the weighting strategies over the simple voting scheme. When comparing the dynamic and the static approaches, results show that the dynamic weighting is superior to the static strategy in terms of classification accuracy.
