I have created a KNN model and a Naive Bays model using my training data. Now I want to compare them using ROC curve and test data, but the problem is my label attribute is polynominal and ROC curve just support binominal !


Is there any way to solve such problem ?

    Hi soheil008,


    the ROC Curve is only defined for a two class problem. There is no ROC curve for more classes.
