Federated Continual Learning Framework for Robust mmWave Human Activity Recognition Under LOS–NLOS Domain Shifts

2025-12-23

Abstract excerpt

Millimeter-wave (mmWave) detection is a widespread human activity recognition (HAR) method. However, due to the mmWave characteristics, it is challenging to per-form HAR in non-line-of-sight (NLOS) environments. Before the prevalence of artificial intelligence (AI) technologies, mmWave-based HAR systems mainly relied on tradi-tional signal processing and handcrafted feature extraction (e.g. time–frequency analy-si...
