Ein Random Forest ist ein Klassifikations- und Regressionsverfahren, das aus mehreren unkorrelierten Entscheidungsbäumen besteht. Alle Entscheidungsbäume sind unter einer bestimmten Art von Randomisierung während des Lernprozesses gewachsen. Für eine Klassifikation darf jeder Baum in diesem Wald eine Entscheidung treffen und die Klasse mit den meisten Stimmen entscheidet die …
