1. Gradient B Boosting Decision Tree/eXtremeGradient Boosting 2021.12.29 Jialin Li

2. Boosting Y=f(x)+L L:redusial function Samples are strongly relative.

3. CART :

4. Gradient Boosting Decision Tree fM(x)= m=1 ?m(?) , Tm is the m tree m is number of trees. M

5. XGboost optimized GBDT 1.L 2. L 3.

6. Application Import xgboost 1. 2. (train and test) 3. Some examples https://github.com/dmlc/xgboost

7. Next to do 1. Try to train with our samples 2. Learn the meaning of parameters (important to adjust the params)

8. Backup GBDT
