摘要:

在潜在系统将受到积极干预的情况下,因果效应的估计是基本的。构建因果推断引擎的一部分是定义变量如何相互关联,也就是说,定义给定条件依赖关系的变量之间的函数关系。在本文中,我们偏离因果模型中的线性关系的共同假设,利用神经自回归密度估计,并使用它们来估计因果关系的珍珠做演算框架内。使用合成数据,我们表明,该方法可以检索因果关系的影响,从非线性系统,而不明确建模的变量之间的相互作用。

英文摘要:

Estimation of causal effects is fundamental in situations were the underlying system will be subject to active interventions. Part of building a causal inference engine is defining how variables relate to each other, that is, defining the functional relationship between variables given conditional dependencies. In this paper, we deviate from the common assumption of linear relationships in causal models by making use of neural autoregressive density estimators and use them to estimate causal effects within the Pearl's do-calculus framework. Using synthetic data, we show that the approach can retrieve causal effects from non-linear systems without explicitly modeling the interactions between the variables.
