"WebHierarchical clustering algorithms produce a nested sequence of clusters, with a single all-inclusive cluster at the top and single point clusters at the bottom. Agglomerative hierarchical algorithms [JD88] start with all the data points as a separate cluster. Each step of the algorithm involves merging two clusters that are the most similar.

WebThe BIRCH authors mention hierarchical clustering, k-means, and CLARANS [19]. For best results, we would want to use an algorithm that not only uses the mean of the clustering feature, but that also uses the weight and variance. The weight can be fairly easily used in many algorithms, WebJun 1, 1996 · BIRCH incrementally and dynamically clusters incoming multi-dimensional metric data points to try to produce the best quality clustering with the available resources (i.e., available memory and time constraints). BIRCH can typically find a good clustering with a single scan of the data, and improve the quality further with a few additional scans.
