标题： Root Cause Analysis of Outliers in Unknown Cyclic Graphs

摘要： 我们研究循环因果图中异常值的传播，将其追溯到一个或几个“根本原因”节点。 我们证明，只要扰动足够强，并且按照正常模式下的相同结构方程传播，就有可能确定一个简短的潜在根本原因列表。 该简短列表包括真正的根本原因以及与其位于同一循环中的根本原因的父节点。 值得注意的是，我们的方法不需要因果图的先验知识。 显示英文摘要

摘要： We study the propagation of outliers in cyclic causal graphs with linear structural equations, tracing them back to one or several "root cause" nodes. We show that it is possible to identify a short list of potential root causes provided that the perturbation is sufficiently strong and propagates according to the same structural equations as in the normal mode. This shortlist consists of the true root causes together with those of its parents lying on a cycle with the root cause. Notably, our method does not require prior knowledge of the causal graph.
