Octave QP issue
I came across a clever trick in the previous classes discussions for improving the stability and results of qp() in Octave. Essentially you just add a tiny amount to the H matrix's diagonal (10^15) and then solve for alpha0 using qp. Then you rerun qp using alpha0 as the initial value and use your original H to obtain the value of alpha.
However, for N=10, I found the percent better for SVM went up by 1520% as a result consistently. This leads to an inbetween value which is on the verge of changing my answer to Q8.
I know this must have come up last time, but I wonder if this possible spread in the results due to implementation issues is accounted for in the answers?
