This is currently my personal site with some random stuffs, maybe it will become a portfolio site when I have enough skills in website programming, I hope.

Not any solutions that I have posted here are correct, they may contain my naive guess and even my fallacies. Take them at your own risk. Anyway, various posts here serve as my personal notes rather than complete articles.

  1. Hi Vy, I was wondering if you have any solutions / pointers with exercise 8.13 from Learning From Data?
    The question is as follows:
    KT complementary slackness gives that if αn*>0, then (xn,yn) is on the boundary of the optimal fat-hyperplane and yn(w*Txn+b*) = 1. Show that the reverse is not true. Namely, it is possible that αn*= 0 and yet (xn,yn) is on the boundary satisfying yn(w*Txn+b*) = 1.
    Hint: Consider a toy data set with two positive examples at (0,0) and (1,0), and one negative example at (0,1).

    1. Sorry, it’s been a long time since my last touch on SVM so I don’t remember much. And I don’t think I had the solution for Exercise 8.13.
