Edit the rules in the "Decision Tree to Ruleset" node

KNIME Analytics Platform
#1

Hi eveybody, I just downloaded the new Knime Version and I think that is fantastic.

I was using the the "Decision Tree to Ruleset" node and I wonder how can I edit the rules for instance, one of the original rule says:
 

"$PAT$ <= 954604.5 AND $PAS$ <= 966195.5 AND $PAT$ <= 2905579.0 => Bin 1"

then I want to change it by, 

"$PAT$ <= 954604.5 AND $PAS$ <= 966195.5 AND $PAT$ <= 2905579.0 => SEGMENT ONE"

I am attaching the node with the workflow and info.

Best Regards

With the Split rules to condition and outcome option, you can have the outcomes in a separate column. With a String Replace (Dictionary) or a Rule Engine node you can add a new outcome column (or replace the old). After that, you can use these columns with the new Rule Engine (Dictionary) node to apply the rules (or create a PMML RuleSet).

Cheers, gabor

Thank you aborg I followed your advice and worked, but I beg you if you check the attached workflow just to know if there is a more efficient way to do it.

Best regards

That looks good, althought the column rename and the string manipulation are not required before Rule Engine (Dictionary). You can check the attached workflow.
