get_support_vector_num_class_svmT_get_support_vector_num_class_svmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvm (Operator)

Name

get_support_vector_num_class_svmT_get_support_vector_num_class_svmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvm — Return the number of support vectors of a support vector machine.

Signature

Description

get_support_vector_num_class_svmget_support_vector_num_class_svmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvm returns in NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectors the number of support vectors that are stored in the support vector machine (SVM) given by SVMHandleSVMHandleSVMHandleSVMHandleSVMHandle. get_support_vector_num_class_svmget_support_vector_num_class_svmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvmGetSupportVectorNumClassSvm should be called before the labels of individual support vectors are read out with get_support_vector_class_svmget_support_vector_class_svmGetSupportVectorClassSvmGetSupportVectorClassSvmGetSupportVectorClassSvm, e.g., for visualizing which the training data become a SV (see get_support_vector_class_svmget_support_vector_class_svmGetSupportVectorClassSvmGetSupportVectorClassSvmGetSupportVectorClassSvm). The number of SVs in each classifier is listed in NumSVPerSVMNumSVPerSVMNumSVPerSVMNumSVPerSVMnumSVPerSVM. The reason that its sum differs from the Number obtained in NumSupportVectorsNumSupportVectorsNumSupportVectorsNumSupportVectorsnumSupportVectors is that SV evaluations are reused throughout different sub-classifiers. NumSVPerSVMNumSVPerSVMNumSVPerSVMNumSVPerSVMnumSVPerSVM provides the possibility for controlling the process of speeding up SVM classification time with the operator reduce_class_svmreduce_class_svmReduceClassSvmReduceClassSvmReduceClassSvm.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

Result

If SVMHandleSVMHandleSVMHandleSVMHandleSVMHandle is valid the operator get_sample_num_class_svmget_sample_num_class_svmGetSampleNumClassSvmGetSampleNumClassSvmGetSampleNumClassSvm returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
