"ReAdd previously filtered Attribute"

sorry if this question is a beginner question, but I couldn´t find a satisfying solution in the manual or the forum yet.

I think it is a basic functionaliy but I couldn´t figure out which operator is necessary.

I filtered a nominal attribute out in order to run a only real-value type input clustering algorithm.
After clustering I want to re-add the nominal attribute and then save the exampleset with the cluster Attribute and my nominal attribute included.

thanks for your help

Hello Thomas

Try something like this:

IOMultiplier to create a copy of ExampleSet
First Set:

Remove nominal attribute
Perform clustering

Switch to second set by using the IOSelector

SecondSet:

Remove every attribute except the nominal one AND the ID-column

Then use ExampleSetJoin to combine both sets.

hope this was helpful

regards,

Steffen

thank you stefan,

thats exactly what I was looking for.
Just didnt get the preprocessing steps before the join right but i supposed that I needed the Join Operator in some way.
But now it works.

thank you for your help
