Re: [Scikit-learn-general] NMF implementation

Hi Olivier, The code looks very well written. I think it would fit well in scikit-learn. The API would have to be modified to fit the scikit-learn format. You can read more about that at the developers' page: http://scikit-learn.org/stable/developers/index.html It will also require some un

Hi Olivier, Just a quick answer (I am on holidays, skying :} ). Please forget me for being a bit direct in this email: I don't have much time in front of the computer. My gut feeling is that the algorithms that you propose are in the scope of the scikit. I do not think that they are a duplication

2012-03-15 Thread Olivier Mangin
Hello, Since I am currently using NMF for my robotics research, I have an implementation of some algorithms from [1]_ that could extend scikit-learn current implementation. More precisely the current implementation covers the Frobenius norm case (for measuring the reconstruction error), and th
