描述

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 该算子 reduce_class_svmreduce_class_svmReduceClassSvmReduceClassSvmReduceClassSvmreduce_class_svm.
