(Sent to wrong mailing list, sorry for duplication) Hi Chaitanya, Yes, Stochastic Gradient Descents algorithm logic is written in Cython. The implementation can be viewed here: https://github.com/scikit-learn/scikit-learn/blob/master/sklearn/linear_mode... Hope that helps, Danny On Wed, Jun 29, 2016 at 10:31 AM, Chaitanya Prasad <chaitanya94@gmail.com> wrote:

Hello

I'm a student currently trying to benchmark a few Black box optimized algorithms against Gradient Descent Algorithms. It would be extremely helpful for me if someone could tell me whether the Stochastic Gradient Descent for scikit has been written in pure Python or whether it has been optmized using Cython in any manner.

Thanks and Regards. Chaitanya
