Hello, is there a way to select the train and validation data separately from the separate data in the workspace for classification learner? Classification Learner interface does it by splitting the train data into %train and %test as a deafult. I need this to take advantage of the classification learner.
Kind regards

You can set the percentage of data to be reserved for testing or even import a test data set through the Test section on the Classification Learner tab. You can refer to these documentation sites for more information :

While creating a new session, you can select holdout validation and select a percentage of data to be used as a validation set. This can help you if you want to set a specific number of samples for validation.
I don't think you can specify the validation data separately as of now.
