There are many methods or routines to find the optimal parameter C for specific training data, such as Cross Validation in LiblineaR. Share. WebBias and Slack The SVM introduced by Vapnik includes an unregularized bias term b, leading to classiﬁcation via a function of the form: f(x) = sign (w ·x +b). In practice, we want to work with datasets that are not linearly separable, so we introduce slacks ξi, just as before.

This is obtained by maximizing the space between classes and the hyper-plane. More importantly, the SVM’s capacity to generalize is superior relative to other methods, and it is capable of evading local minima [13].
