    Hi @maryamen69

    Calculate the Mean Absolute Error is only possible if you have the "true labels". (you are comparing the "true labels" to the "predicted labels")
    This is a priori not the case for unsupervised learning like clustering.
    If not you can use the Performance (classification) operator...

    Hope this helps,

    Regards,

    Hi again @maryamen69,

    Or maybe I misunderstood, by Mean Absolute Error you mean Average within Centroid distance ?
    In this case, you have to use the Cluster Distance Performance operator.
