Is there a scaling function in SVMlight?

Question

The LIBSVM guide states that data sets should be scaled to a certain range before running SVM on them. In Appendix B of the guide, they show a LIBSVM function svm-scale that does the scaling. Is there an equivalent function for SVMlight?

Answer 1

Unfortunately no. You have to standardize the data by yourself. Just keep in mind that use the mean and std of training data in test data scaling.
