Entropy Scorer

Other

Scorer for clustering results given a reference clustering. Connect the table containing the reference clustering to the first input port (the table should contain a column with the cluster IDs) and the table with the clustering results to the second input port (it should also contain a column with some cluster IDs). Select the respective columns in both tables from the dialog. After successful execution, the view will show entropy values (the smaller the better) and some quality value (in [0,1] - with 1 being the best possible value, as used in Fuzzy Clustering in Parallel Universes , section 6: "Experimental results").

Input Ports

  1. Type: Data Table containing reference clustering.
  2. Type: Data Table containing clustering (to score).

Output Ports

  1. Type: Data Table containing entropy values for each cluster. The last row contains statistics on the entire clustering. It corresponds to the table show in the Statistics View.
