Hi
I am trying to use the Classification Learner App within Matlab R2020a for a relatively simple problem. While I can get results I do not see how to split the data into training and validation data sets; only how to do k-folds.
Also, I cannot save my session. I can only export a model. My interface looks different than what is online
Any help is appreciated

Hi Mohamed Trabia,
To split the data into training and validation data sets you should choose the 'holdout validation' option in the validation tab when you create a new session. You can find more information under the 'Choosing Validation Scheme' at the following link:

You can learn more about saving sessions from the 'Save and Open App Session' section at the following link below:

The UI looks different probably because you are using R2020a and MATLAB Online uses R2022b.
