[Scikit-learn-general] performance/scalability of NMF

Are there results about performance and scalability of scikit-learn implementation of NMF? According to this thread on SO http://stackoverflow.com/questions/18575846/non-negative-matrix-factorization-of-sparse-input There are scalability issue. I would be interested to know the biggest dataset

[Scikit-learn-general] Using GraphLASSO with robust correlation estimates

Hi all, I'm using GraphLASSO to estimate the graphical model and precision matrix of my variables. It is well known that GraphLASSO and related methods are very sensitive to contaminated data and their estimates have low break-down points: http://arxiv.org/abs/1501.01219 As suggested by the au
