WebApr 10, 2024 · Gradient Boosting Machines. Gradient boosting machines (GBMs) are … Web1. One option for you would be to increase the learning rate on your models and fit them all the way (using cross validation to select a optimal tree depth). This will give you an optimal model with less trees. Then you can select which set of variables you want based on these two models, and fit an more careful model with a small learning rate ...

Feature importance scores can be used for feature selection in … WebA remark on Sandeep's answer: Assuming 2 of your features are highly colinear (say equal 99% of time) Indeed only 1 feature is selected at each split, but for the next split, the xgb can select the other feature. Therefore, the xgb feature ranking will probably rank the 2 colinear features equally.
