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. WebMay 5, 2014 · BIRCH algorithm is a clustering algorithm suitable for very large data sets. In the algorithm, a CF-tree is built whose all entries in each leaf node must satisfy a uniform threshold T, and the CF ...
