Abstract

Bei einem Verfahren zur Ermittlung von Clustern (8a, 8b, 8c, 9a, 9b, 9c) in Sensordaten mittels eines eingebetteten Systems wird zur Reduzierung des Ressourcenverbrauchs das Bilden der Cluster (8a, 8b, 8c, 9a, 9b, 9c) sequentiell durchgeführt, wobei die gebildeten Cluster (8a, 8b, 8c) beim Bilden von neuen Clustern (9a, 9b, 9c) in Abhängigkeit einer weiteren Merkmalraumdimension verändert werden.
