Description
get_params_class_svmget_params_class_svmGetParamsClassSvmGetParamsClassSvmget_params_class_svm returns the parameters of a support
vector machine (SVM) that were specified when the SVM was created
with create_class_svmcreate_class_svmCreateClassSvmCreateClassSvmcreate_class_svm. This is particularly useful if the
SVM was read from a file with read_class_svmread_class_svmReadClassSvmReadClassSvmread_class_svm. The output of
get_params_class_svmget_params_class_svmGetParamsClassSvmGetParamsClassSvmget_params_class_svm 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_svmCreateClassSvmCreateClassSvmcreate_class_svm.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

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