Suppport Vector Machine Problem about ml-from-scratch HOT 2 OPEN

And idx = lagr_mult > 1e-7 create an error too using the last dataset. I modified it to idx = lagr_mult > 1e-11. But it isn t a good solution.

1. Did you normalize your data before you used rbf kernel?

2. In your example, there are 3 classes (0, 1, 2). If you removed one class (say 0) and then ran the implementation, your accuracy would improve greatly.

3. On this website (https://pythonprogramming.net/soft-margin-kernel-cvxopt-svm-machine-learning-tutorial/), the code is pretty identical with a couple of slight differences.. anyhow, running this code with with how you created your dataset yielded a WORSE accuracy. On the bottom of the page, the author wrote that this SVM code is meant to display the inner workings and not for robust usage. So similarly, this is applied here.
