Many to One (PMML)

KNIME Base Nodes version 4.2.2.v202009241438 by KNIME AG, Zurich, Switzerland

Transforms the values of multiple columns into a single column depending on the include method and documents the transformation in PMML. If set to binary the condensed column's value is set to the name of the first column with value 1. If the include method is maximum or minimum the value of the condensed column is set to the name of the column which, of all included columns, has the largest or smallest value. If the include method is binary and all columns are 0 the condensed column will contain a missing value.
