Number to Category (Apply)

This node takes columns with integer data and maps every number to the former category string. The information for the value mapping is taken from the PMML model.

This node is typically used to apply the same mapping found by a Category To Number node.

Options

Append columns: If checked, the computed columns will be appended to the input table. Otherwise the computed columns replace their source columns.
Column suffix: The column name of the computed columns are the name of the column in the input appended by this suffix.

Input Ports

: PMML document containing value mapping
: Data

Output Ports

: Pass-through of the incoming PMML document
: Data with transformed columns
