Integriertes Training

Trainieren von Deep-Learning-Netzen mit integrierten Trainingsfunktionen

Nachdem Sie die Netzarchitektur definiert haben, können Sie die Trainingsparameter mit der Funktion trainingOptions festlegen. Sie können das Netz dann mit der Funktion trainnet trainieren. Verwenden Sie das trainierte Netz, um Klassenbezeichnungen oder numerische Antworten vorherzusagen.
