Understanding Q4

I am not sure I understand Q4. It's referring to the two classifiers in Q2 and Q3. But Q2 and Q3 have 5 classifiers each. One classifier for 0 versus all, one for 1 versus all, etc. So which pair are we computing the difference between the number of support vectors?

Re: Understanding Q4

My interpretation is use the two classifiers from your answers to questions 2 and 3. For example, let's say 4 vs all had the highest E_in on question 2, and 7 vs all had the lowest E_in on question 3. For question 4, you would compute the difference between the number of support vectors for the 4 vs all case and the 7 vs all case. I hope that helps!
