Tree boosting is a highly effective and widely used machine learning method. In this paper, we describe a scalable end-to-end tree boosting system called XGBoost, which is used widely by data scientists to achieve state-of-the-art results on many machine learning challenges. We propose a nove...

自此从代码角度交代了前文《xgboost: A Scalable Tree Boosting System论文及源码》的作者的具体实现思路,希望能够进一步加深对boosting方法的理解。目前最新的进展为XGBoost4J-Spark发布进一步融入Spark的应用场景中(2016/10/26)见附录[3],后续的发展会继续跟进。PS. TreeRefresher 代码中未见引用这里不做进一步介绍。
This is an introductory document of using the xgboost package in R.xgboost is short for eXtreme Gradient Boosting package. It is an efficient and scalable implementation of gradient boosting framework by (Friedman, 2001) (Friedman et al., 2000). The package includes efficient linear model solver...
