xgboost原理

  xgboost是一个提升模型,即训练多个分类器,然后将这些分类器串联起来,达到最终的预测效果。每一个基分类器都是一个弱分类器,但是很多串联起来后效果很强大。

  每次加入一棵新树是为了让目标函数进一步下降。当然,加入了新树之后obj可以反映当前损失值;那么这棵新树如何分裂呢?可以使用泰勒公式构造一个Gain来决定当前树模型的划分。

xgboost和gbdt的区别

  • 传统GBDT以CART作为基分类器,xgboost还支持线性分类器,这个时候xgboost相当于带L1和L2正则化项的逻辑斯蒂回归(分类问题)或者线性回归(回归问题)。
  • 传统GBDT在优化时只用到一阶导数信息,xgboost则对代价函数进行了二阶泰勒展开,同时用到了一阶和二阶导数。顺便提一下,xgboost工具支持自定义代价函数,只要函数可一阶和二阶求导。
  • xgboost在代价函数里加入了正则项,用于控制模型的复杂度。正则项里包含了树的叶子节点个数、每个叶子节点上输出的score的L2模的平方和。从Bias-variance tradeoff角度来讲,正则项降低了模型的variance,使学习出来的模型更加简单,防止过拟合,这也是xgboost优于传统GBDT的一个特性。
  • 列抽样(column subsampling)。xgboost借鉴了随机森林的做法,支持列抽样,不仅能降低过拟合,还能减少计算,这也是xgboost异于传统gbdt的一个特性。
  • 对缺失值的处理。对于特征的值有缺失的样本,xgboost可以自动学习出它的分裂方向
  • xgboost工具支持并行。boosting不是一种串行的结构吗?怎么并行的?注意xgboost的并行不是tree粒度的并行,xgboost也是一次迭代完才能进行下一次迭代的(第t次迭代的代价函数里包含了前面t-1次迭代的预测值)。xgboost的并行是在特征粒度上的。我们知道,决策树的学习最耗时的一个步骤就是对特征的值进行排序(因为要确定最佳分割点),xgboost在训练之前,预先对数据进行了排序,然后保存为block结构,后面的迭代中重复地使用这个结构,大大减小计算量。这个block结构也使得并行成为了可能,在进行节点的分裂时,需要计算每个特征的增益,最终选增益最大的那个特征去做分裂,那么各个特征的增益计算就可以开多线程进行。
