Hi Charles. That is unrelated to the GSoC mail you responded to, right? I think updating liblinear sound like a good idea, if it doesn't end up being to complicated. Allowing instance weights is certainly something we'd like to have. You should check how far our code diverged, but I think for

Does anybody know of further optimization approaches that were not mentioned below and that we could consider? Maybe parallel computing. A grid search is an embarrassingly parallel problem. A Bayesian optimization is not. We have the necessary framework only to tackle embarrassingly parallel

Yes, your suggestion is viable, but I have not seen any algorithms in sklearn that use y like that in fit method. ​​ I would have thought in the case of Mahalanobis distances that transform would transform each feature such that the resulting feature space was Euclidean. ​Exactly. Thus,
