Indeed this is quite a new method and we have a policy to wait a bit to see if it's actually practically useful before including an implementation in the code base. Michal, if you have replicated the results of the paper in Python it would be interesting to publish your code in a scikit-learn styl

It would be nice to have it implemented in a sklearn.random_projections-compatible form, but is there reason to believe it is stable/popular enough for inclusion in the repo? On 30 October 2014 00:24, Michal Romaniuk wrote: > Hi everyone, > > I'm thinking of adding the Unrestricted Fast Johnson-
