| Abstract: | To improve the classification performance,a novel SVM ensemble learning algorithm based on discretization method and selective ensemble approach is proposed.This algorithm uses the discretized data sets obtained by the rough sets and boolean reasoning method to construct individual SVMs with good diversity,which can improve the performance of ensemble learning.After every SVM is trained separately,a selective approach to SVM ensemble is utilized to reduce the ensemble size and to improve its performance.Experimental results show that the presented algorithm achieves better performance than do the traditional ensemble learning methods such as Bagging and Adaboost. |
