Frequently Asked Questions

How does a gradient boosting regressor work?

Gradient boosting regressors are a type of inductively generated tree ensemble model. At each step, a new tree is trained against the negative gradient of the loss function, which is analogous to (or identical to, in the case of least-squares error) the residual error.

How does gradient boosting work with scikit-learn?

In this post, you will get a general idea of gradient boosting machine learning algorithm and how it works with scikit-learn. The term ‘ Boosting ‘ refers to a group of algorithms to create strong predictive models. By using a weak learner, it creates multiple models iteratively.

What's the difference between XGBoost and sklearn gradient boosted?

You are correct, XGBoost ('eXtreme Gradient Boosting') and sklearn's GradientBoost are fundamentally the same as they are both gradient boosting implementations. However, there are very significant differences under the hood in a practical sense.
