Intermediate Topic 24 of 51 AI & Machine Learning
Gradient Boosting
Sequentially adding models that correct earlier errors.
How it works
Builds trees sequentially, each fitting the residual errors (gradients) of the ensemble; XGBoost, LightGBM and CatBoost dominate tabular competitions.
Where it is used
Ranking, fraud, tabular prediction.
Common pitfall
Prone to overfitting without learning rate, depth and early-stopping tuning.
Where it fits in the course
Gradient Boosting is topic 24 of 51 in AI & Machine Learning, rated Intermediate. It follows Random Forests. The next topic is Feature Engineering.
