Abstract: Feature subset and parameters are often selected manually in classification problem based on support vector machine(SVM) and least square support vector machine(LS-SVM),which is very time consuming.In this paper,an automatic method for selecting the parameter subset and parameters of LS-SVM based on genetic algorithms is presented.The selection of feature subset and parameters is automatic by means of the whole seeking ability of genetic algorithm,which provides an effectual approach to the selection of fea...
