摘要:

结构因果模型被广泛用于因果建模,但它们与其他建模工具的关系却知之甚少。在本文中,我们提供了一个新的视角常微分方程和结构因果模型之间的关系。我们展示了如何,在一定条件下,一个常微分方程的渐近行为下的非常数的干预可以使用动态结构因果模型建模。与早期的工作相比,我们不仅研究干预对平衡状态的影响;相反,我们建模的渐近行为是动态的干预下,随时间变化,并包括作为一个特殊情况下的静态平衡的研究。

英文摘要:

Structural Causal Models are widely used in causal modelling, but how they relate to other modelling tools is poorly understood. In this paper we provide a novel perspective on the relationship between Ordinary Differential Equations and Structural Causal Models. We show how, under certain conditions, the asymptotic behaviour of an Ordinary Differential Equation under non-constant interventions can be modelled using Dynamic Structural Causal Models. In contrast to earlier work, we study not only the effect of interventions on equilibrium states; rather, we model asymptotic behaviour that is dynamic under interventions that vary in time, and include as a special case the study of static equilibria.
