@Title(value="Hierarchical clustering by label") @Description(value="Cluster points by a (pre-assigned!) label. For comparing results with a reference clustering.") public class ByLabelHierarchicalClustering
Pseudo clustering using labels. This "algorithm" puts elements into the same cluster when they agree in their labels. I.e. it just uses a predefined clustering, and is mostly useful for testing and evaluation (e.g. comparing the result of a real algorithm to a reference result / golden standard). This variant derives a hierarchical result by doing a prefix comparison on labels. TODO: Noise handling (e.g. allow the user to specify a noise label pattern?)
