What I mean is in "multi-class" case.
If a instance is : 3,5,7,11,25,35 1:10, 2:30....
So it finally belongs to "only one" class?
Case 1, ie. this instance just belongs to class 3.
Case 2, or this instance belongs to some of those classes,like 3, 11, 25
Is the homework one dealing with the case 1 or case 2?
I am confusing now.
Thinks for answering.
