Kapitel 4. Überlegungen zur Validierung von Miningmodellen
In diesem Kapitel:
Validierungstechniken 54
Darstellung von Validierungsergebnissen 56
Zusammenfassung 58
Wie bereits gezeigt wurde, können mittels Data Mining Vorhersagen anhand von Erfahrungswerten generiert werden. Diese Vorhersagen dürfen allerdings nicht unreflektiert verwendet werden. Vielmehr gilt es deren Vertrauenswürdigkeit zu prüfen. Dieses Kapitel zeigt gängige Ansätze zur Validierung von Miningmodellen, welche unter anderem auch von SQL Server Analysis Services unterstützt werden, auf. Daneben werden Möglichkeiten zur Darstellung von Validierungsergebnissen besprochen.
