WebSep 1, 2024 · Abstract. BIRCH clustering is a widely known approach for clustering that has influenced much subsequent research and commercial products. The key contribution of BIRCH is the Clustering Feature tree (CF-Tree), which is a compressed representation of the input data. As new data arrives, the tree is eventually rebuilt to increase the … WebJul 28, 2016 · 1 Answer. Sorted by: 2.
