Gradient Boosting

Gradient Boosting er en ensemble-læringsmetode, formaliseret af Jerome H. Friedman i 2001, der kombinerer en sekvens af svage lærende — typisk lavvandede beslutningstræer — således at hvert nyt træ tilpasses for at minimere residualfejlene fra de foregående træer. Det er kernealgoritmen bag populære implementeringer som XGBoost, LightGBM og CatBoost.
