单元选择:案例研究及与A/B测试启发式的比较

Unit Selection: Case Study and Comparison with A/B Test Heuristic

University of California Los Angeles(加州大学洛杉矶分校)

Ang Li, Judea Pearl

摘要:

Li和Pearl定义的单位选择问题确定了具有期望的反事实行为模式的个体,例如,如果受到鼓励,个体会积极响应,否则不会。Li和Pearl通过实例说明了他们的单元选择模型是超越A/B检验的。本文揭示了A/B检验算法的本质,它是Li和Pearl定义的效益函数的特例。此外,我们提供了更多的模拟使用情况下,李珍珠的单元选择模型,以帮助决策者正确地应用他们的模型,说明A/B测试的技巧,通常是有问题的。

英文摘要:

The unit selection problem defined by Li and Pearl identifies individuals who have desired counterfactual behavior patterns, for example, individuals who would respond positively if encouraged and would not otherwise. Li and Pearl showed by example that their unit selection model is beyond the A/B test heuristics. In this paper, we reveal the essence of the A/B test heuristics, which are exceptional cases of the benefit function defined by Li and Pearl. Furthermore, We provided more simulated use cases of Li-Pearl's unit selection model to help decision-makers apply their model correctly, explaining that A/B test heuristics are generally problematic.
