KNIME Distance Matrix Extension version 4.2.1.v202008251158 by KNIME AG, Zurich, Switzerland
Hierarchically clusters the input data using a distance matrix.
Note: This node works only on small data sets, because it has cubic complexity.
There are two methods to do hierarchical clustering:
In order to determine the distance between clusters a measure has to be defined. Basically, there exist three methods to compare two clusters:
The distance information used by this node is either read from a distance vector column that must be available in the input data or is computed directly with usage of a connected distance measure. You can always calculate the distance matrix using the corresponding calculate node.
To use this node in KNIME, install KNIME Distance Matrix from the following update site:
