I used a high value for C, otherwise it regularizes. Observed that in libsvm case it regularized so much that E_in was never zero. So I suppressed regularization by choosing a high value of C.
From Prof's lecture, I recall that the high value of C ensures that slackness is penalized heavily, so as to achieve hard margin.
