boosted_trees_regression early stop

User 1766 | 5/13/2015, 10:12:57 PM

If I set maxiterations_ to be very big, after some point score on the validation set will stop improving. Is it possible in graphlab-create to realize such a feature that iterations will stop after N iterations, in which validation score did not improve, where N is parameter ?

The feature you mention is definitely on our road-map and we are actively working on it. Our first priority was to ensure that validation set metric tracking is performed for all models. With GLC 1.4, you should have validation metric tracking for most models. We plan to incorporate more metrics along with early stopping in the upcoming releases.
