CP-逻辑中的实际因果关系

Actual Causation in CP-logic

Lessius Mechelen(梅赫伦勒西厄斯大学学院)

摘要:

给定某个领域的因果模型和在该领域发生的一个特定事件,实际因果关系的问题是确定某种结果的可能原因中哪一个实际上导致了它,Halpern和Pearl在结构模型的背景下开发了这个问题最有影响力的方法之一。在本文中,我认为这实际上不是研究这个问题的最佳设置。作为替代,我提供了CP逻辑的概率逻辑程序设计语言。与结构模型不同,CP逻辑包含了偏差/默认的区别,这通常被认为是实际因果关系的一个重要方面,并且它具有显式的动态语义,这有助于将作为实际因果关系问题输入的故事形式化。

英文摘要:

Given a causal model of some domain and a particular story that has taken place in this domain, the problem of actual causation is deciding which of the possible causes for some effect actually caused it. One of the most influential approaches to this problem has been developed by Halpern and Pearl in the context of structural models. In this paper, I argue that this is actually not the best setting for studying this problem. As an alternative, I offer the probabilistic logic programming language of CP-logic. Unlike structural models, CP-logic incorporates the deviant/default distinction that is generally considered an important aspect of actual causation, and it has an explicitly dynamic semantics, which helps to formalize the stories that serve as input to an actual causation problem.
