AI总结:

本文旨在研究结构因果模型下因果熵与因果信息增益的基本数学性质,提出了因果条件熵等定义并分析了界限与链式法则,为增强因果机器学习任务奠定理论基础。

摘要:

近期的研究进展使得在给定结构因果模型(SCM)的情况下能够量化因果控制。这是通过引入一些量来实现的,这些量编码了当对另一个变量进行干预时,某一个变量的熵的变化。这些被称为因果熵和因果信息增益的测度,旨在解决现有信息论方法在因果性起关键作用的机器学习任务中的局限性。然而,它们尚未得到适当的数学研究。我们的研究通过建立和分析这些概念的基本性质(包括界限和链式法则),为因果熵和因果信息增益的形式化理解做出了贡献。此外,我们阐明了因果熵与随机干预之间的关系。我们还提出了因果条件熵和因果条件信息增益的定义。总体而言,这一探索为通过研究基于因果性考量的新近信息论量来增强因果机器学习任务铺平了道路。

英文摘要:

Recent developments enable the quantification of causal control given a structural causal model (SCM). This has been accomplished by introducing quantities which encode changes in the entropy of one variable when intervening on another. These measures, named causal entropy and causal information gain, aim to address limitations in existing information theoretical approaches for machine learning tasks where causality plays a crucial role. They have not yet been properly mathematically studied. Our research contributes to the formal understanding of the notions of causal entropy and causal information gain by establishing and analyzing fundamental properties of these concepts, including bounds and chain rules. Furthermore, we elucidate the relationship between causal entropy and stochastic interventions. We also propose definitions for causal conditional entropy and causal conditional information gain. Overall, this exploration paves the way for enhancing causal machine learning tasks through the study of recently-proposed information theoretic quantities grounded in considerations about causality.
