Discovering Interpretable Semantics from Radio Signals for Contactless Cardiac Monitoring
Advanced Science, EarlyView.This study presents a semantic representation framework for clinically interpretable cardiac monitoring from contactless radio signals. It formulates radio semantic learning as an information‐bottleneck problem and approximates the objective via intra‐modal compression and cross‐modal alignment, structuring radio measurements into meaningful semantic ...
