Gradient Boosting と XGBoost
Gradient Boosting や XGBoostについて調べたことをまとめました． Gradient Descent や Newton法と絡めて説明していきたいと思います． 目次 Boosting Gradient Descent (Steepest Descent) Gradient Boosting Regression Tree Gradient Tree Boosting Learning rate Newton Boosting XGBoost Generalization Error Conclusion Reference Boosting Boostingとは，ランダムより少し良い程度の”弱い”学習アルゴリズムを使って， そのアルゴリズムよりも”強い”学習アルゴリズムをつくることです． イメージとしては，弱い学習アルゴリズムを”boost”してあげる感じでしょうか．
