算法：Xgboost提升算法 1 1 Xgboost算法概述

[@shaz-z506]

Hi, I can see that you have explained xgboost in a very intuitive way, but could you add an English subtitle it will be much helpful.

[@Fan-fb4tz]

讲得挺清楚，但是请标明你ppt里的图还有公式从哪里来的，尊重原创作者和知识（今天刚读到Tianqi Chen的Xgboost paper，发现你的图和公式直接从他的论文里复制过来的）

so what's the different between AdaBoost and gradient boost??

[@marvellousmoonvalley7085]

Gradient Boost uses a decision tree. Adaboost uses a decision stump, which is simpler than a decision tree.
