Correlation-Based Leakage Screening is Insufficient for IoT/IIoT Intrusion-Detection Benchmarks: Evidence of Redundant Shortcut Encoding in Edge-IIoTset
Machine-learning intrusion detection for the Internet of Things (IoT) and Industrial IoT (IIoT) routinely reports near-perfect accuracy on public benchmarks, yet the feature-level basis of that performance is rarely interrogated. This study benchmarks four supervised classifiers, random forest, gradient boosting, logis...
