Hi all

I am using a classification model where the performance output is a confusion matrix.

But the number of classified records in the confusion table is much less that what was presented to the model. Would anybody have any idea why this would happen? I can send an example if required?

    the number of records in the confusion matrix depends on the number of records presented to the respective "Apply Model" operator. That's because only there the model is applied and "tested". Does that help?

    All the best,
