I was also recently bit by this scale_C business. It looks like the decision to make scale_C=True the un-changeable default has already been made, but when this is done *PLEASE* make this abundantly clear in the documentation... my understanding was that the C in the SVM equation means the thing that Ian referred to, and which libSVM uses, and shogun, etc... rather than this "conveniently scaled" alternative. Maybe this new parameter should be renamed to something other than "C" so that SVC(C=foo) fails rather than computes a surprising thing? Anyway, I'm sure this is off-topic, but if someone could point me to a more appropriate discussion thread I'd appreciate it.
