[R] polynomial svms and in-sample error

2012-11-16 Thread Jessica Streicher
Hi again! This might be more of a statistical question, but anyway: If i train several support vector machines with different degrees of polynomials, and as result, get that higher degrees not only have a higher test error, but also a higher in-sample error, why is that? I would assume i

Actually i think i found the problem, its something about the probability model again as it seems, if you just take the normal predictions everythings good. Man does that probability stuff absolutely not work properly. Any suggestions how to do ROC curves without it? Or am i just generally
