Some attribute is missing the input from example set

Hello,

I have a simple RM process, and whenever I use the set role operator I get the warning message "The attribute loan_status is missing in the input example set". I can run a model, but the performance operator gives me a confusion matrix full of zeros. How can I fix this?  I checked the data and it is binominal, the conversion was well performed. 

Regards,
Bernardo

    Hi Bernardo,

    No apologies necessary! I've got both now. 

    Regarding location of Set Role, it is fine as is. The only thing is just to make sure you've got "include special attributes" turned on in Map, as you already have.

    In general your process can be simplified a little, and removing the data duplication. This can be done using the unmatched data from the Filter Examples operator as shown in the screenshot below. The top data takes the non-missing examples, then the unmatched gives the examples with missing loan status.



    Regarding polynominal to binominal, are you wanting to do this to all variables? There shouldn't be a need to do this to loan status as the software will be able to tell by default that this binominal.

    The performance operator gives all zeros as it compares the predicted label to actual. You're scoring data where there is no actual label, hence no performance metric.

    Any further questions or clarifications please let me know.

    Best,

    Roland
