classify_class_svm — Classify a feature vector by a support vector machine.
classify_class_svm computes the best Num classes of
the feature vector Features with the SVM SVMHandle
and returns them in Class. If the classifier was
created in the Mode = 'one-versus-one', the
classes are ordered by the number of votes of the sub-classifiers. If
Mode = 'one-versus-all' was used, the classes are ordered
by the value of each sub-classifier (see create_class_svm for more
details). If the classifier was created in the Mode =
'novelty-detection', it determines whether the feature vector
belongs to the same class as the training data (Class = 1) or is
regarded as outlier (Class = 0). In this case Num must be
set to 1 as the classifier only determines membership.
Before calling classify_class_svm, the SVM must be trained
with train_class_svm.
SVMHandle (input_control) class_svm → (handle)
SVM handle.
Features (input_control) real-array → (real)
Feature vector.
Num (input_control) integer-array → (integer)
Number of best classes to determine.
Default value: 1
Suggested values: 1, 2, 3, 4, 5
Class (output_control) integer(-array) → (integer)
Result of classifying the feature vector with the SVM.
If the parameters are valid the operator classify_class_svm
returns the value 2 (H_MSG_TRUE). If necessary, an exception is
raised.
