CART( Classification And Regression Tree) is a kind of data mining algorithm with high accuracy and efficiency. It supports of discrete and continuous data classification,but it cannot be applied to classify encrypted private cloud data. Therefore,PPCART( Privacy-preserving CART) is proposed,that is...

一.论文《QuickScorer:aFast Algorithm to Rank Documents withAdditive Ensembles of Regression Trees》是为了解决LTR模型的预测问题,如果LTR中的LambdaMart在生成模型时产生的树数和叶结点过多,在对样本打分预测时会遍历每棵树,这样在线上使用时效率较慢,这篇文章主要就是利用了bitvector方法加速打分预测。代码我找了...
