Key Takeaways

Explainability matters for anomaly detection: When AI systems flag unusual patterns in complex data, organizations need reliable methods to understand why something was flagged as abnormal. This paper addresses a real gap—existing explanation tools often struggle with high-dimensional data or incorrectly highlight irrelevant features, potentially leading to misdiagnosis.
The proposed BREAD method outperforms current approaches: The researchers demonstrate that their baseline-referenced diagnosis method achieves "higher faithfulness in detecting the features causing the anomaly compared to LIME" (a widely-used explanation tool). This means it more accurately identifies which data features actually drove the anomaly detection, reducing false leads in diagnosis.
Mathematical guarantees provide confidence: Unlike many AI explanation methods that rely purely on empirical validation, this approach includes "mathematical guarantees" for accuracy under mean-shift anomaly conditions. This theoretical foundation is important for high-stakes applications where organizations need confidence that explanations are trustworthy, not just plausible.
Scalability enables real-world deployment: The method is designed to be "scalable" and "model-agnostic," meaning it can work across different AI detection systems without requiring custom redesign. This practical advantage makes responsible AI more feasible for organizations already using diverse AI tools for monitoring.
Diagnosis accuracy directly impacts decision-making: By generating more accurate explanations of anomalies, this method helps human operators make better-informed decisions about whether flagged issues require intervention, reducing both false alarms and missed problems.

Abstract

Artificial Intelligence (AI)-based prospective anomaly detection methods are increasingly deployed in high-dimensional and nonlinear settings. Among these approaches, AI-based statistical process monitoring (SPM) is widely used, providing a structured framework for prospective monitoring. Once an anomaly is detected, a diagnosis method is needed to identify the features driving the flagged observation away from normal behaviour. Traditional SPM diagnosis methods are typically designed for specific detection models and cannot be directly applied to AI-based methods. Model-agnostic explainable AI (XAI) offers a general framework for feature relevance explanation. However, existing methods suffer from scalability limitations or assign relevance to noise features, reducing diagnosis accuracy. We propose a scalable, baseline-referenced diagnosis method that uses both the anomalous observation and normal baseline information. We provide mathematical guarantees that under a mean-shift anomaly setting, the proposed method achieves higher faithfulness in detecting the features causing the anomaly compared to LIME. Simulation studies and a real-world case study validate the effectiveness of the proposed method and show that it generates more faithful and accurate diagnosis results for AI-based prospective anomaly detection methods.
