Cross Validation replaces Split Data

erik_van_ingen

Just checking. I understand that Cross Validation does a n-fold 'Split-Data-train-apply model'. Does this literally mean that if you use Cross Validation, it will replace the 'manual' Split Data? Therefore you use one or the other?

Hi @erik_van_ingen ,

Cross validation serves the same purpose than the simple split. The implementation looks slightly different, since it is something very similar to a loop. Please have a look at this video to get some guidance: https://academy.rapidminer.com/courses/validation-demo

Best,
