AUC Calculation within Auto Model

Dear Community, 

is there a possibility within the Auto Model function to generate the AUC quality measure by parallely computing selected classification models? I couldn't find the option to select the performance paramters like e.g. the F-Score, the AUC and so on.   



Thank you in advance for your support! 

Best regards!

    Hi @Muhammed_Fatih_,

    If you can not get the AUC score it is maybe because your problem is NOT a binary classification problem (in a binary classification problem the label has only two possible values - TRUE/FALSE, YES/NO, 1/0 etc.).
    In your case, it seems that your problem is a multi-class classification problem : The number of possible values of your label is strictly greater than 2.In this case , in Auto-Model you only have access to the Accuracy and the classification error.

    Regards,

    Hi @lionelderkrikor

    thank you for your answer! My problem is in fact a binary classification problem with two target classes that should be predicted. 

    Does the AUC score normally exist in the Auto Model or is the AUC only available via the binary performance operator in the pipeline? 

    Many thanks and best regards!

    Hi @lionelderkrikor, 

    perfect! The AUC appeared in the result layer of Auto Model as you mentioned. It confused me that the user cannot choose it before. Nevertheless it is automatically generated in case of a binary problem.
