Description

get_params_class_svmget_params_class_svmget_params_class_svmGetParamsClassSvmGetParamsClassSvm returns the parameters of a support vector machine (SVM) that were specified when the SVM was created with create_class_svmcreate_class_svmcreate_class_svmCreateClassSvmCreateClassSvm. This is particularly useful if the SVM was read from a file with read_class_svmread_class_svmread_class_svmReadClassSvmReadClassSvm. The output of get_params_class_svmget_params_class_svmget_params_class_svmGetParamsClassSvmGetParamsClassSvm can, for example, be used to check whether the feature vectors and, if necessary, the target data to be used with the SVM have the correct lengths. For a description of the parameters, see create_class_svmcreate_class_svmcreate_class_svmCreateClassSvmCreateClassSvm.

Result

If the parameters are valid the operator get_params_class_svmget_params_class_svmget_params_class_svmGetParamsClassSvmGetParamsClassSvm returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
