I would like to know how to do a pairwise classification.
I have 3 classes A,B and C. I have samples for each class. Now I would like to build a classifier in such a way that given a new test sample, my model should say the probability of it belong to class A or B, B or C and C or A.
Is there a way to do it?
Or is there a way to say my test image definitely doesn't belong to a particular class and thus i can say it belongs to any of the other two classes.
