Hierarchical Cluster Assigner

Predictor

Assigns clusters to rows based on an hierarchical clustering. You may either select a fixed number of cluster or enter a distance threshold. If the latter is used then all clusters in the dendrogram will be used that have the smallest distance to the threshold but are below it. The threshold is given as a normalized distance between 0 and 1. All distances are normalized based on the maximum distance.
Note that the assigner only assigns the same data that has been used for clustering to clusters. It is not capable of assigning unseen data.

Input Ports

  1. Type: Cluster Tree

Output Ports

  1. Type: Data
