hi,

In apply model operator, I assume cutoff probability for classification is 0.5 in 2-class case, and the highest probability in more than 2 classes case...

is there any way to set the classification cutoff by hand? e.g if its more than 0.3 to yes, it is yes, otherwise no?

    Fred,

     

    sure. Have a look at Create Threshold & Apply Threshold.

     

    Further interesting are operators like Drop Uncertain, Find Threshold and Select Recall.
