XGBoost: A Scalable Tree Boosting System
xgboost : A Scalable tree Boosting SystemTianqi ChenUniversity of GuestrinUniversity of Boosting is a highly effective and widely used machinelearning method. In this paper, we describe a Scalable end-to-end tree Boosting System called xgboost , which is usedwidely by data scientists to achieve state-of-the-art resultson many machine learning challenges. We propose a novelsparsity-aware algorithm for sparse data and weighted quan-tile sketch for approximate tree learning. More importantly,we provide insights on cache access patterns, data compres-sion and sharding to build a Scalable tree Boosting combining these insights, xgboost scales beyond billionsof examples using far fewer resources than existing Machine Learning1. INTRODUCTIONM achine learning and data-driven approaches are becom-ing very important in many areas.
