How Does Sci-Kit Learn Train Regression Neural Networks (MLPRegressor) So Fast?












1












$begingroup$


Why does using the scikit-learn library's MLPRegressor result in such a boost in training time when compared to constructing the network from scratch? I tried both methods and I found that writing the code from scratch yielded an average training time of ~10 seconds while Sci-Kit Learn trained almost instantly?

    My suspicion would be that Scikit-Learn utilises a lot of numpy, which in turn utilises C (I could be wrong about that!) - a high-performant low-level language.

    If I was to code an ANN from scratch in C then do you think it would perform about the same as Scikit-learn (Not that I'll actually do that!)

    If you are intelligent enough and know how to optimize your code like hell, then Yes, Just check their Source code simple to see :)
