Root Cause Analysis of Outliers in Unknown Cyclic Graphs

arXiv:2510.06995v2 Announce Type: replace-cross Abstract: 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 t

Why this matters
Why now

The increasing complexity of AI systems and their integration into critical infrastructure necessitates robust methods for identifying the root causes of anomalies and ensuring reliability.

Why it’s important

This research provides a foundational step towards building explainable and reliable autonomous AI systems by improving anomaly detection and diagnostics in complex networks.

What changes

The ability to accurately trace outliers to their root causes, even in unknown cyclic graphs, moves us closer to AI systems that can self-diagnose and potentially self-correct.
