Birch algorytm
WebThe BIRCH algorithm [23,24,22] is a widely known cluster analysis approach, that won the 2006 SIGMOD Test of Time Award. It scales well to big data even with limited resources because it processes the data as a stream and aggregates it into a compact summary of the data. BIRCH has inspired many subsequent WebJan 1, 2012 · BIRCH algorithm has three main stages: 1. Given the threshold T, the clustering space. is divided into the initial clusters in such a way. that cluster radius is smaller than R. BIRCH uses.
