DEM: A Distilled Explanation Model for Interpretable Anomaly Detection in Physiological Sensor Networks

arXiv:2605.31007v1 Announce Type: new Abstract: Anomaly detection in physiological sensor data from Wireless Body Area Networks (WBANs) can be caused by sensor faults, network disruptions, or missing data, leading to false alarms. Hence, it demands both high predictive accuracy and clinically interpretable explanations. Existing approaches rely either on black-box models that achieve strong performance but offer no transparency, or on post-prediction explanation methods such as SHAP and LIME. In this paper, we propose the Distilled Explanation Model (DEM), a three-stage glass-box framework tha

Why this matters
Why now

The increasing complexity of AI models in critical applications like physiological monitoring demands both high accuracy and clear interpretability, leading to new research in explainable AI.

Why it’s important

Improving the interpretability of AI in sensitive areas like healthcare reduces false alarms and builds trust, which is crucial for wider adoption and regulatory acceptance of AI in medical diagnostics.

What changes

The focus is shifting from purely performance-driven AI models to those that inherently offer transparent explanations, impacting how AI systems are designed and deployed in real-world scenarios.
