Parameter optimisation with X-Partitioner

Hi, I’m new in the knime community, I have a machine learning subject in my last year of informatics. The have asigned me a project where I have to extract a variable ‘mininstances’ from the decision tree and then pass it to all the other techniques as the number min of nodes. The problem is that I don’t know how to set up the loops. Can anyone help me please?

Hello @cMarchante,

Welcome to the community!

If you need to extract the variable ‘mininstances’, it sounds like it is already provided to you. The variable should be passed as a flow variable and you will be able to select that flow variable in your other methods. Is this variable meant for the amount of iterations to be done in a loop?

Or is it meant to be passed into the X-Partitioner to tell it how many times it should loop.
