Introduction
Gradient Boosting Decision Tree is a machine learning technique for regression and classification problems, which produces a prediction model in the form of an ensemble of basic learning models, typically decision trees.
Decision Tree: e.g.
eXtreme Gradient Boosting (XGBOOST) is an efficient implementation of Gradient Boosting method, a scalable, portable and distributed GB library, and it was started as a research project by Tianqi Chen.
