Beschreibung

select_feature_set_trainf_mlp_protectedselect_feature_set_trainf_mlp_protectedSelectFeatureSetTrainfMlpProtectedselect_feature_set_trainf_mlp_protectedSelectFeatureSetTrainfMlpProtectedSelectFeatureSetTrainfMlpProtected wählt die optimalen Merkmale für ein bestimmtes OCR-Klassifikationsproblem aus. Die Daten für das OCR-Klassifikationsproblem werden mit der Trainingsdatei TrainingFileTrainingFileTrainingFileTrainingFileTrainingFiletrainingFile ausgewählt. Als Klassifikator wird ein mehrschichtiges Perzeptron (MLP) verwendet.

Die Funktionalität des Operators entspricht der Funktionalität von select_feature_set_trainf_mlpselect_feature_set_trainf_mlpSelectFeatureSetTrainfMlpselect_feature_set_trainf_mlpSelectFeatureSetTrainfMlpSelectFeatureSetTrainfMlp, mit der Erweiterung, dass select_feature_set_trainf_mlp_protectedselect_feature_set_trainf_mlp_protectedSelectFeatureSetTrainfMlpProtectedselect_feature_set_trainf_mlp_protectedSelectFeatureSetTrainfMlpProtectedSelectFeatureSetTrainfMlpProtected sowohl ungeschützte als auch geschützte Trainingsdateien verarbeiten kann. Geschützte Trainingsdateien können nur mit dem korrekten Benutzerpasswort PasswordPasswordPasswordPasswordPasswordpassword verwendet werden. Falls genau ein Passwort PasswordPasswordPasswordPasswordPasswordpassword übergeben wird, werden alle Eingabedateien TrainingFileTrainingFileTrainingFileTrainingFileTrainingFiletrainingFile mit diesem Passwort überprüft, ansonsten muss die Anzahl der Passworte gleich der Anzahl der Eingabedateien sein, und die Eingabedatei an Position n wird mit dem Passwort an Position n überprüft. Für ungeschützte Trainingsdateien werden die übergebenen Passworte ignoriert.

Für eine genauere Beschreibung der Operatorfunktionalität siehe select_feature_set_trainf_mlpselect_feature_set_trainf_mlpSelectFeatureSetTrainfMlpselect_feature_set_trainf_mlpSelectFeatureSetTrainfMlpSelectFeatureSetTrainfMlp. Das Konzept des Schützens von OCR-Trainingsdaten in HALCON ist in protect_ocr_trainfprotect_ocr_trainfProtectOcrTrainfprotect_ocr_trainfProtectOcrTrainfProtectOcrTrainf beschrieben.

Achtung

Die Laufzeit dieses Operators kann mit größeren Datensätzen und einer längeren Merkmalsliste unter Umständen sehr lang sein.

Es ist zu beachten, dass dieser Operator nicht aufgerufen werden sollte, wenn für das Training nur ein kleiner Datensatz verfügbar ist. Auf Grund des Risikos der Überanpassung kann der Operator select_feature_set_trainf_mlp_protectedselect_feature_set_trainf_mlp_protectedSelectFeatureSetTrainfMlpProtectedselect_feature_set_trainf_mlp_protectedSelectFeatureSetTrainfMlpProtectedSelectFeatureSetTrainfMlpProtected zwar einerseits einen Klassifikator mit sehr hohem Score liefern. Andererseits weist der Klassifikator jedoch eine schlechte Erkennugsrate auf, wenn dieser getestet wird.

Parallelisierung

Dieser Operator liefert ein Handle zurück. Es ist zu beachten, dass der Zustand einer Instanz dieses Handletyps durch bestimmte Operatoren geändert werden kann, obwohl das Handle als Eingabeparameter in diesen Operatoren verwendet wird.
