def evaluate_class_svm(svmhandle: HHandle, 特征: Sequence[float]) -> Sequence[float]
def evaluate_class_svm_s(svmhandle: HHandle, 特征: Sequence[float]) -> float
描述
evaluate_class_svmevaluate_class_svmEvaluateClassSvmEvaluateClassSvmEvaluateClassSvmevaluate_class_svm calculates for a feature vector
provided in 特征特征特征特征特征特征 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.
运行信息
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.

Result of evaluating the feature vector with the SVM.
结果
If the parameters are valid the operator evaluate_class_svmevaluate_class_svmEvaluateClassSvmEvaluateClassSvmEvaluateClassSvmevaluate_class_svm
returns the value 2 (
H_MSG_TRUE)
. If necessary, an exception is
raised.
