| Abstract: | The spreading capacity of support vector machine(SVM) depends largely on the selection of kernel function and its parameters,and penalty factor,that is model selection.Having analyzed the parameter's influence on the classifier's recognition accuracy,we propose a new method for SVM model selection using genetic algorithm and empirical error minimization.The experiments on 13 different UCI benchmarks show its correctness,effectiveness and good spreading performance. |
