In this paper, we propose a novel density-based clustering method in which we deal with data appearing sequentially. In data mining, a cluster is a high-density region gathering a set of objects which are similar according to a prefixed criterion. For purposes of modelling, we restrict a ...

Recently, a lot of density-based clustering algorithms are extended for data streams. The main idea in these algorithms is using densitybased methods in the clustering process and at the same time overcoming the constraints, which are put out by data stream's nature. The purpose of this paper...
