: : If k = 1, the prediction will be the set of the closest point

This is called multi-label.. Were you in my lecture last week??
And my answer is for the multi-label case!!
Chih-Jen
: 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.
