Correct Attribute Type to Binominal

Created: 2010-05-14 07:27:59

This process will first generate some artificial data to show a commonly known problem:

Some attributes have only two values, but are not correctly stored as Binominal, instead RapidMiner recognizes them as nominal. In order to use them for some special operators, we have to change this to binominal. We can achieve this by using the Nominal to Binominal operator with the the parameter transform_binominals switched off. Please take a look at the data before and after the Nominal to Binominal operator.
