+====== Differences between libLinear and libSVM: ======
+When the bias term learned using libLinear (-B 1) is regularized and is appended to the end of the weight vector, there does not appear to be a way to learn an unregularized bias term with libLinear. However, libSVM is able to learn a bias term rho in the decision function sign(w<sup>T</sup> x - rho).
