WebJul 24, 2024 · Out of all clustering algorithms, only Density-based (Mean-Shift, DBSCAN, OPTICS, HDBSCAN) allows clustering without specifying the number of clusters. The algorithms work via sliding windows moving toward the high density of points, i.e. they find however many dense regions are present. WebCluster analysis is a primary method for database mining. It is either used as a stand-alone tool to get insight into the distribution of a data set, e.g. to focus further analysis and data …
