Cross Validation replaces Split Data

erik_van_ingen

只是检查。我你nderstand 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.www.turtlecreekpls.com/courses/validation-demo

Best,
