Name
get_support_vector_num_class_svmT_get_support_vector_num_class_svmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvmget_support_vector_num_class_svm — Return the number of support vectors of a support vector machine.
Signature
def get_support_vector_num_class_svm(svmhandle: HHandle) -> Tuple[int, Sequence[int]]
Description
get_support_vector_num_class_svmget_support_vector_num_class_svmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvmget_support_vector_num_class_svm returns in
NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectorsnum_support_vectors the number of support vectors that are
stored in the support vector machine (SVM) given by
SVMHandleSVMHandleSVMHandleSVMHandleSVMHandlesvmhandle. get_support_vector_num_class_svmget_support_vector_num_class_svmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvmget_support_vector_num_class_svm should
be called before the labels of individual support vectors are read
out with get_support_vector_class_svmget_support_vector_class_svmGetSupportVectorClassSvmGetSupportVectorClassSvmGetSupportVectorClassSvmget_support_vector_class_svm, e.g., for visualizing
which the training data become a SV (see
get_support_vector_class_svmget_support_vector_class_svmGetSupportVectorClassSvmGetSupportVectorClassSvmGetSupportVectorClassSvmget_support_vector_class_svm). The number of SVs in each
classifier is listed in NumSVPerSVMNumSVPerSVMNumSVPerSVMNumSVPerSVMnumSVPerSVMnum_svper_svm. The reason that its
sum differs from the Number obtained in NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectorsnum_support_vectors
is that SV evaluations are reused throughout different
sub-classifiers. NumSVPerSVMNumSVPerSVMNumSVPerSVMNumSVPerSVMnumSVPerSVMnum_svper_svm provides the possibility for
controlling the process of speeding up SVM classification time with
the operator reduce_class_svmreduce_class_svmReduceClassSvmReduceClassSvmReduceClassSvmreduce_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 SVMHandleSVMHandleSVMHandleSVMHandleSVMHandlesvmhandle is valid the operator
get_sample_num_class_svmget_sample_num_class_svmGetSampleNumClassSvmGetSampleNumClassSvmGetSampleNumClassSvmget_sample_num_class_svm returns the value 2 (
H_MSG_TRUE)
. If
necessary, an exception is raised.
