On the Fly Detection of Root Causes from Observed Data with Application to IT Systems

1 code implementation9 Feb 2024 Lei Zan, Charles K. Assaad, Emilie Devijver, Eric Gaussier

This paper introduces a new structural causal model tailored for representing threshold-based IT systems and presents a new algorithm designed to rapidly detect root causes of anomalies in such systems.
