Birch algorytm
WebBIRCH is a hierarchical algorithm (the only such algorithm included in the present project). Being hierarchical, BIRCH outputs not a single set of most-probable clusters, but an entire “hierarchy” of partitions of clusters. At the root of the tree of this hierarchy is a partition with a single cluster that includes all input elements (even ... WebBIRCH (balanced iterative reducing and clustering using hierarchies) is an unsupervised data mining algorithm used to perform hierarchical clustering over particularly large data-sets. An advantage of BIRCH is its ability to incrementally and dynamically cluster incoming, multi-dimensional metric data points in an attempt to produce the best quality clustering …
