Proposes a novel Support Vector Machine (SVM) ensemble algorithm based on discretization method, this algorithm uses the rough sets and boolean reasoning approach, which is controlled by the consistency level coined from the rough sets theory, to construct base classifiers with good diversity so that the performance of ensemble learning can be improved. Experimental results show that the proposed algorithm has better classification performance than single SVM. Compared with the traditional ensemble learning methods such as Bagging and Adaboost, this novel ensemble method also has better classification accuracy.
