I thought it would be nice to have a way to check if we're on the right track with problems 2-5 without giving away the answers. I ran SVM (with the polynomial kernel) for a couple of cases and pasted the results below. Are others getting the same numbers?
0 vs 7 classifier, C=0.01, Q=2
number of support vectors = 861
= 0.071778
= 0.063241
2 vs 8 classifier, C=0.1, Q=3
number of support vectors = 721
= 0.234878
= 0.291209
