[scikit-learn] RidgeCV and cv=LeaveOneGroupOut

[Christophe Pallier]

Hello,

I do not manage to find out how to use a LeaveOneGroupOut crossvalidation
stratergy with RidgeCV. The problem is that I do not see how to pass the
groups mapping.

Any hint?
The approach by GridSearch is way to slow to be practical.

Thanks in advance!

PS: Thanks Alex for the response to my previous question. By the way, the
context is fMRI data, so I am running the Ridge regression in about 200.000
voxels.
