Nelson Liu 376aa50e70 [MRG+1] feature: add beta-threshold early stopping for decision tree growth (#6954) ... * feature: add beta-threshold early stopping for decision tree growth * check if value of beta is greater than or equal to 0 * test if default value of beta is 0 and edit input validation error message * feature: separately validate beta for reg. and clf., and add tests for it * feature: add beta to forest-based ensemble methods * feature: add separate condition to determine that beta is float * feature: add beta to gradient boosting estimators * rename parameter to min_impurity_split, edit input validation and associated tests * chore: fix spacing in forest and force recompilation of grad boosting extension * remove trivial comment in grad boost and add whats new * edit wording in test comment / rebuild * rename constant with the same name as our parameter * edit line length for what's new * remove constant and set min_impurity_split to 1e-7 by default * fix docstrings for new default * fix defaults in gradientboosting and forest classes		2016-07-27 17:46:49 +02:00
