WebBIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm that performs hierarchical clustering over large data sets. With … Webters in a linear scan of the dataset. The algorithm is further optimized by removing outliers e ciently. BIRCH assumes that points lie in a metric space and that clusters are spherical in shape. The CF-tree is composed of CF nodes, where CF stands for \clustering feature." A clustering feature CF i is simply a triple fN i;LS i;SS igwhere N i is
