Unüberwachtes Lernen und Vorverarbeitung
Die zweite Gruppe von Algorithmen für maschinelles Lernen, die wir betrachten werden, sind Algorithmen für unüberwachtes Lernen. Unter diesen Begriff fallen sämtliche Arten von maschinellem Lernen, bei denen das Ergebnis unbekannt ist und es keinen Lehrer zum Trainieren des Algorithmus gibt. Beim unüberwachten Lernen erhält der Lernalgorithmus lediglich die Eingabedaten und wird damit beauftragt, Wissen aus diesen Daten zu extrahieren.
Arten von unüberwachtem Lernen
Wir werden uns in diesem Kapitel zwei Arten unüberwachten Lernens ansehen: Transformationen des Datensatzes und Clusterverfahren.
Unüberwachte Transformationen eines Datensatzes sind Algorithmen, die eine neue Repräsentation der Daten ...
