AI总结:

本文提出首个基于Rischel形式化的SCM间因果抽象学习框架,采用可微编程联合求解组合子问题,并在合成及电动汽车电池制造现实任务中验证了其优于独立和顺序方法。

摘要:

抽象可用于关联表示同一系统在不同分辨率水平上的两个结构因果模型。学习能够保证相对于干预分布具有一致性的抽象,将允许人们在尊重潜在因果关系的同时,跨多个粒度水平联合推理证据。在本文中,我们基于Rischel(2020)最近提出的抽象形式化,首次提出了SCM之间因果抽象学习的框架。在此基础上,我们提出了一种可微编程解决方案,该方案联合求解多个组合子问题,并在合成设置以及与电动汽车电池制造相关的具有挑战性的现实问题上,研究了该方法相对于独立和顺序方法的性能与优势。

英文摘要:

An abstraction can be used to relate two structural causal models representing the same system at different levels of resolution. Learning abstractions which guarantee consistency with respect to interventional distributions would allow one to jointly reason about evidence across multiple levels of granularity while respecting the underlying cause-effect relationships. In this paper, we introduce a first framework for causal abstraction learning between SCMs based on the formalization of abstraction recently proposed by Rischel (2020). Based on that, we propose a differentiable programming solution that jointly solves a number of combinatorial sub-problems, and we study its performance and benefits against independent and sequential approaches on synthetic settings and on a challenging real-world problem related to electric vehicle battery manufacturing.
