Question

The soft margin formulation for a support vector machine is the following i-1 E8Y What happens to the margin as C infinity? Choose one: A. Behaves like a hard margin B. Goes to infinity C. Goes to zero D. None of the above

Answer 1

if c goes to infinity then it behaves like hard margin

option - A

C is a trade-off between training error and the flatness of the solution. The larger C is the less the final training error will be.

C is a regularization parameter:

— small C allows constraints to be easily ignored → large margin

— large C makes constraints hard to ignore → narrow margin

— C = ∞ enforces all constraints: hard margin
