Using an external validation set in classification learner

Hello,

The usual way to validate your model in the classification learner is to use one of the two options i.e. k-fold cross validation or hold out validation.

However I would like to use my own validation set I have prepared. Can you tell me how to do that in the classification learner?

Thanks a lot for your help.

Regards,

Ludovic.

Starting in R2026a, your own validation set can be specified using the "ValidationPartition" Name-Value pair when starting the Classification Learner app from the command line. See https://www.mathworks.com/help/releases/R2026a/stats/classificationlearner-app.html for more details.
