PMML Gradient Boosted Trees Predictor

StreamableDeprecatedDecisions Tree Ensembles for KNIME version 4.2.0.v202004061016 by KNIME AG, Zurich, Switzerland

Applies classification from a Gradient Boosted Trees model that is provided in PMML format. Note that it is currently not possible to load models that were learned on a bit-, byte- or double-vector column and then written to PMML because PMML does not support vector columns. The implementation follows the algorithms described in "Greedy Function Approximation: A Gradient Boosting Machine" by Jerome H. Friedman (1999)". For more information you can also take a look at this .

Options

Check this option if you want to use a custom name for the column containing the prediction
Prediction column name
Name of the output column containing the prediction.
Append overall prediction confidence
Appends a column that contains information on how the certain the model is about its prediction.
Append individual class probabilites
Appends for each possible class a column containing the probability that the given row is an element of this class
Suffix for probability column
Allows to add a suffix for the class probability columns.
