ECG-LDC: A Hardware-Efficient Low-Dimensional Computing Framework for ECG Arrhythmia Classification

This arXiv feed contains multiple signal-processing and ML papers with clear security and privacy relevance. Notable items: (1) "Track-Consistency-Based GNSS RFI Monitoring Using Crowdsourced ADS-B Sensor Networks" demonstrates a scalable method to detect GNSS radio-frequency interference (RFI) events from 605M ADS‑B reports and found event clusters coincident with a NOTAM, indicating crowdsourced ADS‑B networks can provide complementary RFI situational awareness even when receiver quality indicators remain high. (2) "Physics‑Informed Structure Anchoring... for Cross‑Environment RF Fingerprint
