AutoFi: Towards Automatic WiFi Human Sensing via Geometric Self-Supervised Learning. (arXiv:2205.01629v1 [cs.NI])
cs.LG updates on arXiv.org arxiv.org
WiFi sensing technology has shown superiority in smart homes among various
sensors for its cost-effective and privacy-preserving merits. It is empowered
by Channel State Information (CSI) extracted from WiFi signals and advanced
machine learning models to analyze motion patterns in CSI. Many learning-based
models have been proposed for kinds of applications, but they severely suffer
from environmental dependency. Though domain adaptation methods have been
proposed to tackle this issue, it is not practical to collect high-quality,
well-segmented and balanced CSI …
