Gradient boosting with jax
WebXGBoost stands for “Extreme Gradient Boosting”, where the term “Gradient Boosting” originates from the paper Greedy Function Approximation: A Gradient Boosting Machine, by Friedman. The … WebGradient Boosting was initially developed by Friedman 2001, and the general algorithm is referred to as Algorithm 1: Gradient_Boost, in that paper. Furthermore, we also discussed how to develop a practical Gradient Boosting procedure, based upon the absolute difference loss function, and Decision Tree weak learners.
