    Hi @heretolearn,

    In general, we use some form of validation to understand if the trained model performs similarly on some sort of testing or hold-out set. We do this to check performance is similar on a representative dataset that the model hasn't seen whilst training.

    We have some nice resources on RapidMiner Academy on model validation: https://academy.rapidminer.com/learn/dashboard?query=validation

    Hope this helps. Happy to point you towards something particular if needed.

    Best,
    Roland
