这种排序目标在uplift建模 (uplift modeling, UM)文献中常遇到。learning to rank(L2R)技术源自信息检索,专门设计用于直接优化预测排序质量,而不是用于对样本进行排序的预测值的质量 。这篇文章探讨了L2R技术是否可以在UM环境中成功使用。 因果分类和uplift建模 相关工作 设有n 个样本的数据集 D={(x,y,t)} ,...
1.将uplift model当前使用的评估指标从两个维度划分:(1)treatment组和control组是否放在一起评估;(2)增益值是以当前绝对样本量计算的还是以整体样本量 2.标准learning to rank(ltr)技术在学习auuc方面是有能力的模型,更进一步作者提出了promoted cumulative gain(PCG)来当做ltr的优化指标,该指标在auuc方面比传统ltr的...

The samples were sorted by the rank of the estimated CATE values, and subsamples consisting of top k samples (k = 1, 2, …, n; n, total sample size) were created for each value of k. The uplift curve f(k) plots the estimated difference in PONV events between the treated and...

To overcome dimensionality issues (Yadav et al., 2020), ensemble-based reduced-rank square-root methods (Ravela & McLaughlin, 2007; Ravela et al., 2010) are employed. 3.2 Upslope Orographic Precipitation Estimation We use the upslope model (Roe, 2005) for estimating orography-induced ...
Uplift Model 概念顾名思义,uplift 可以理解为增益或者增量,uplift model 即为 增量模型。其通常用于评估某种干预对个体的状态/行为的因果效应,也就是 Individual Treatment Effect,即 ITE。假设在某个 framew…
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,虽然从原理和解释性上都十分的完备,但是它们看起来都不够具有一般性,即每种算...
