Reference WF for cross-validation and parameter optimisation

Hey guys

I’m familiar with the work-flow for cross-validation and the one for param- optimization but does anyone have a WF where it performs both for the same algorithm ? (XGboost in my case)

Best, Chris

Hello Chris,

how about this one?

It uses SVMs but you should be able to replace the SVM nodes with the algorithm of your choice.
