The issue isn't about the SVMs; it's about the hinge_loss function in sklearn.metrics. All you need to do is plug in the formula from Wikipedia (except with the wy replaced by precomputed scores) and update the documentation. Btw., the Wikipedia page has a reference to Crammer and Singer's paper [1], which actually discusses their multiclass SVMs. [1] http://jmlr.csail.mit.edu/papers/volume2/crammer01a/crammer01a.pdf ------------------------------------------------------------------------------ _______________________________________________ Scikit-learn-general mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/scikit-learn-general
