Parse Numbers


Synopsis

Maps all nominal values to numerical values by parsing the numbers if possible.


Description

This operator transforms nominal attributes into numerical ones. In contrast to the NominalToNumeric operator, this operator directly parses numbers from the wrongly as nominal values encoded values. Please note that this operator will first check the stored nominal mappings for all attributes. If (old) mappings are still stored which actually are nominal (without the corresponding data being part of the example set), the attribute will not be converted. Please use the operator Guess Types in these cases.
