The comparison of optimizing SVM by GA and grid search
As we known, SVM is fit for the application of fault diagnosis. In our paper, we discussed the optimization methods for SVM. Including GA, Grid Search, and K-fold Cross Validation. For optimizing SVM, it is necessary to find out the best kernel function, to pick out the best kernel parameters and pe...

Summary: | As we known, SVM is fit for the application of fault diagnosis. In our paper, we discussed the optimization methods for SVM. Including GA, Grid Search, and K-fold Cross Validation. For optimizing SVM, it is necessary to find out the best kernel function, to pick out the best kernel parameters and penalty factor parameters. Here, the standard datasets of UCI is used to illustrate the optimization effect by GA and Grid Search. The experiment environment is Matlab 2014a, the library of libsvm is adopted. The results can be seen that the Grid Search method has better performance than genetic algorithm in this circumstance. |
