Default Re: Odd results using LibSVM on Prob 8

Thanks for your suggestions, Ilya, Anand & Anne.

I'll try making the cost parameter C high. So far I only tried C=1.0 and 0.5
I've seen that the SV's that the LibSVM package identifies cannot be equidistant to any linear equation. All their alpha values are identical.

In my implementation I do the training, which creates the model and then do a test with the exact same file as the training file. The testing uses the model file created by LibSVM. Thus alpha's and the parameter b etc. are transparent and I don't mess with them. The only possibility of errors is if some wrong parameter or errors in the input.
