Hi, It was a cosmetic variant: 'weights' and 'coefficients' mean the same for linear models. And as iterations are done in a logarithmic way, the x axis was correct to a scaling.
None the less, I fixed the example to be less confusing: https://github.com/scikit-learn/scikit-learn/commit/f924d3e466305ba1eb26e2fadb84eb54225a0437 Thanks Gaël On Tue, Apr 30, 2013 at 05:44:19AM +0100, _ Rolpher wrote: > I'm looking at the example page for Lasso and ElasticNet ( http:// > scikit-learn.org/0.11/auto_examples/linear_model/ > plot_lasso_coordinate_descent_path.html ).
