This is the second post in Boosting algorithm. In the previous post, we go through the earliest Boosting algorithm - AdaBoost, which is actually an approximation of exponential loss via additive stage-forward modelling. What if we want to choose othe…

引言 GBDT已经有了比较成熟的应用,例如XGBoost和pGBRT,但是在特征维度很高数据量很大的时候依然不够快.一个主要的原因是,对于每个特征,他们都需要遍历每一条数据,对每一个可能的分割点去计算信息增益.为了解决这个问题,本文提出了两个新技术:Gradient-based One-Side Sampling(GOSS)和Exclusive Feature Bundling(EFB). Histogram-based Algorithm 基于直方图的方法比基于预排序的方式要更加高效,这里对这…
