A new research paper identifies a critical failure mode in pruned intrusion detectors for Internet-of-Things (IoT) devices, termed "Input-Layer Starvation." The study demonstrates that while overall accuracy may only slightly decrease, per-class performance and macro-F1 scores can plummet significantly due to damage to the first layer of the detector. This issue arises when the first layer's weights are excessively pruned, leading to misattributions and a higher false-alert rate, a problem that can be mitigated by protecting these initial weights or recomputing normalization statistics.
