Have this request:

Feature request: parameter optimisation with Strings

Hi Knimers, I wonder if you can add String parameters to the optimization loop. For Example, During Random Forest parameter Optimisation, I would also like to give Split criteria to the mix and only way to do that is to use proxy variables which makes it more confusing. ( Like 1 = Gini, 2= InformationGain …etc) Being able to define String parameters would definitely ease the pain. Keep up the good work my dear friends.

This looks like a split off from your other thread:

Parameter Optimisation of e.g. Qualitiy Measure using the Rule Engine

Hello guys! I am trying to optimise the parameters. The Quality Measure and the Pruning from the Decision Tree Learner Node. Example for the Quality Measure to test whether the Gini Index or Gain ratio leads to a higher accuracy. To do this, I have the parameter in the optimisation loop, then I try to define the whole thing in the rule engine, but unfortunately this doesn’t work, do you know why this could be? I cant select Replace Column and get an error all the time. (Pictures and workfl…

To keep the forum tidy I’ll close this thread. Let’s keep the conversation going over there.
