Abstract: The parameters setting for Support Vector Machine(SVM) in a training process impacts on the classification accuracy. The selection problem of SVM parameters is considered as a compound optimization problem. Immune algorithm is an efficient random global optimization technique. It has nice performances such as avoiding local optimum, high precision solution, and quick convergence. This paper proposes an immune algorithm applied to model selection of SVM. This algorithm includes clonal selection, hyper-mutation and receptor editing. Experimental results indicate that this method significantly improves the classification accuracy of SVM.
