+1 for a PR
Do you know of other fast estimators I can use

Thanks for the suggestion of how to change RFE.py to exploit warm_start.
Should I add this feature to rfe.py and make a pull request? Or is this
functionality too specialized?
As we said in the issue you opened recently, SGDRegressor doesn't monitor

warm_start can be used but you hav
Hey, I've found that RFECV does a good job of selecting features, but that
it's quite slow. It is quicker if it's used with a fast estimator. For
example, I've found that SGDRegressor is much faster than SVR. I was
wondering any regressor is faster than SGDRegressor (for dense features).
