evaluate_class_svm( : : SVMHandle, Features : Result)

描述

evaluate_class_svmevaluate_class_svmEvaluateClassSvmEvaluateClassSvmEvaluateClassSvmevaluate_class_svm calculates for a feature vector provided in FeaturesFeaturesFeaturesFeaturesfeaturesfeatures the ResultResultResultResultresultresult given a SVM in SVMHandleSVMHandleSVMHandleSVMHandleSVMHandlesvmhandle. The operator evaluate_class_svmevaluate_class_svmEvaluateClassSvmEvaluateClassSvmEvaluateClassSvmevaluate_class_svm can only be used if the SVM was created in the ModeModeModeModemodemode = 'novelty-detection'"novelty-detection""novelty-detection""novelty-detection""novelty-detection""novelty-detection". If the feature vector lies in the class, a ResultResultResultResultresultresult value bigger 1.0 is returned. If the feature vector lies outside the class boundary, e.g., is an outlier, a value smaller 1.0 is returned.

执行信息

多线程类型：可重入（与非独占算子并行运行）。
多线程作用域：全局（可从任何线程调用）。
未采用并行化处理。

参数

SVMHandleSVMHandleSVMHandleSVMHandleSVMHandlesvmhandle (输入控制) class_svm → (handle)

SVM 句柄。

FeaturesFeaturesFeaturesFeaturesfeaturesfeatures (输入控制) real-array → (real)

Feature vector.

ResultResultResultResultresultresult (输出控制) real(-array) → (real)

Result of evaluating the feature vector with the SVM.

结果

如果参数有效，算子 evaluate_class_svmevaluate_class_svmEvaluateClassSvmEvaluateClassSvmEvaluateClassSvmevaluate_class_svm 返回值 2 ( H_MSG_TRUE )。如有必要，则抛出异常。
