Question 11
I have used LIBSVM; the answer that I get is one of a) to d) if I scale it appropriately. However, if I scale it, the margin in the transformed domain is not any more +/1 at the support vectors. So technically the answer proposed is right (since it separates the points with a maximum margin) but it doesn't satisfy the requirement that the margins be +/ 1 at the support vectors.
