Which? lars_path or lasso_path or my proposition?
What I propose in an faster and almost (in the sense that it's not
computed via sgd and coefs may vary) drop-in replacement for
lasso_path.
In fact, some months ago I was trying to do parameter selection for
Lasso using lasso_path and found it quite slow. I did the
interpolation by hand from lars_path, and it became very fast, so I
thought that'd may be worth of a PR.
