马尔可夫链中的概率原因

Probabilistic causes in Markov chains

Christel Baier, Florian Funke, Simon Jantsch, Jakob Piribauer, Robin Ziemek

摘要:

本文研究了马尔可夫链中原因的概率概念,它依赖于反事实性原理和概率提高属性。这一概念的动机是利用原因进行监测,目的是在错误或不受欢迎的行为实际发生之前发现这些行为。原因是系统的一组有限执行,在此之后,结果的概率超过给定的阈值。我们介绍了多种类型的成本,从不同的角度捕捉资源的消耗,并研究了计算成本最小的原因的复杂性。

英文摘要:

The paper studies a probabilistic notion of causes in Markov chains that relies on the counterfactuality principle and the probability-raising property. This notion is motivated by the use of causes for monitoring purposes where the aim is to detect faulty or undesired behaviours before they actually occur. A cause is a set of finite executions of the system after which the probability of the effect exceeds a given threshold. We introduce multiple types of costs that capture the consumption of resources from different perspectives, and study the complexity of computing cost-minimal causes.
