Probably that's what got me confused, I am used to thinking of gradient descent algorithms in terms of perceptrons. But since you already had SGDClassifier, it might have made sense to subclass it - that ensures code reuse and also enough room to add fancy methods. Is that the case? Anyhow, in the SGDClassifier, where does the training happen? Is is here - https://github.com/jaidevd/scikit-learn/blob/master/sklearn/linear_model/stochastic_gradient.py#L362 Also, what is meant by an unbalanced dataset? > > ------------------ > Vlad N. > http://vene.ro > > > > > > ------------------------------------------------------------------------------ > Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond.
