R-Learner 步骤二:损失函数优化 R-Learner 完整实现流程 总结 参考 系列回顾 在因果推断笔记(一) - Uplift Modeling with Meta-Learning Method(T-Learner/S-Learner/X-Learner) 这篇文章中,我们介绍了几种经典的元学习方法用于构建 uplift model。但是无论是 S-Learner,T-Learner 又或者是改进版的 X-Learner,...
r-learner 原理 r-learner是因果推断领域中的一个重要概念,它是基于受限的倾向评分的因果推断方法。在因果推断中,我们通常希望从观察数据中推断出某个因果关系,而r-learner就是用来解决这个问题的一种方法。 r-learner的原理基于双重机器学习(Double Machine Learning)框架,它的核心思想是通过两个机器学习模型来对处理...
R-Learner新定义了一个变量 m^(x) ,英文为“conditional mean outcome”,即condition on协变量X下的响应均值: m^(x)=E(Y|X=x)=μ^0(Xi)+e^(Xi)τ^(Xi) 。根据上面两个公式我们可以得到如下等式,这个公式也是文中最重要的一个推导结果: Yi−m^(Xi)=(Wi−e^(Xi))τ^(Xi)+ϵi(Wi) 在...
