Birch algorytm
WebBIRCH Algorithm Phases The primary phases of BIRCH are: Phase 1: – BIRCH scans the database to build an initial in-memory CF tree Phase 2: Hierarchical Methods – BIRCH applies a (selected) clustering algorithm to cluster the leaf nodes of the CF tree, which removes sparse clusters as outliers and groups dense clusters into larger ones.
