   Hi @morf1us - Just curious. Did you notice the impurity measures logic in decisionTree.dml? The implementation in this PR and that one is same?
   
   Docs are here: https://apache.github.io/systemds/site/algorithms-classification.html#decision-trees
   
   https://github.com/apache/systemds/blob/b8d4897b2d46c5ae34a6d69772a66ad009feee54/scripts/builtin/decisionTree.dml#L264-L348
