Description

evaluate_class_svmevaluate_class_svmEvaluateClassSvmevaluate_class_svmEvaluateClassSvmEvaluateClassSvm calculates for a feature vector provided in FeaturesFeaturesFeaturesFeaturesFeaturesfeatures the ResultResultResultResultResultresult given a SVM in SVMHandleSVMHandleSVMHandleSVMHandleSVMHandleSVMHandle. The operator evaluate_class_svmevaluate_class_svmEvaluateClassSvmevaluate_class_svmEvaluateClassSvmEvaluateClassSvm can only be used if the SVM was created in the Mode = '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.
