„Minimale Anzahl der Datensätze pro untergeordneter Verzweigung“ im C5.0-Modellierungsknoten: Prozentuale Angabe ermöglichen

Bei großer Eingabedatenmenge und einem Prädiktor mit vielen Ausprägungen kann es bei der C5.0-Modellierung leicht zu Abbrüchen kommen, wenn das geeignete Pruning fehlt. Dieses ist u.a. beeinflussbar über die Expertenoption

„Minimale Anzahl der Datensätze pro untergeordneter Verzweigung“, die den sehr niedrigen Standardwert 2 hat.

Leider ist dieser Wert nur als absolute Anzahl, nicht aber als Prozentsatz angebbar, so dass man bei geänderter Eingabedatenmenge jedes Mal den C5.0-Modellierungsknoten ändern muss. Eine Möglichkeit zur prozentualen Angabe ist daher wünschenswert.
