Unfortunately, that isn't supported directly in the Classification Learner. But you can export your trained model to the MATLAB workspace, predict on a set of held-out data there, and identify which observations were misclassified.

Thanks Bernhard for your answer. I experimented this solution with success while waiting for an answer. I understand that the Classification Learner App may have those kind of limitations. Marc
