Abstract :
Although many clustering algorithms have been proposed, seldom is focused on incremental databases. This paper introduces an outlier factor based clustering algorithm, OFCA, which can discover clusters with outlier factor parameters determined easily. An incremental clustering algorithm, IOFCA, is also presented to apply to periodically incremental environment.
