SHAP enhanced transformer GWO boosting model for transparent and robust anomaly detection in IIoT environments
This study introduces a hybrid AI framework for anomaly detection in Industrial IoT (IIoT) environments, combining a temporal transformer encoder, Grey Wolf Optimizer (GWO) for feature selection, and Logistic Boosting classifier. The model achieves 98.2% accuracy, 96.7% precision, 97.1% recall, and an F1-score of 0.969 on a six-month real-world dataset. It demonstrates superior robustness against data drift, maintaining high performance with only 3.2% accuracy degradation under maximum drift conditions, significantly outperforming traditional and deep learning baselines. The framework also provides SHAP-based explainability, ensuring transparent anomaly alerts and aiding root-cause analysis for industrial operators, making it suitable for secure and adaptive industrial systems.
