Of course there are many parameter choices which control how the SVM will be trained. The Matlab help is a litte bit wage about how the parameters archive a better training result. TīmeklisCVSVMModel is a ClassificationPartitionedModel cross-validated SVM classifier. By default, the software implements 10-fold cross-validation. Alternatively, you can cross-validate a trained ClassificationSVM classifier by passing it to crossval. Inspect one of the trained folds using dot notation. CVSVMModel.Trained {1}
