Few-Shot RF Fingerprint Authentication via Unfolded Sparse Recovery

In this paper, we propose a few-shot authentication framework based on radio-frequency fingerprint identification (RFFI). Unlike conventional RFFI approaches, which often memorize device-specific features, our framework learns to accurately compare over-the-air (OTA) signals from different Internet of Things (IoT) devi...

SenseAgent: An LLM Agent for Adaptive Cross-Domain IMU Sensing

This design converts cross-domain IMU sensing from a fixed inference pipeline into a closed-loop sensing process that diagnoses target shifts, selects suitable sensing actions, and rejects unsafe adaptations.

CSI-Agent: LLM-Assisted Few-Shot Adaptation for Cross-Domain Wi-Fi CSI Sensing

This work proposes CSI-Agent, an evidence-seeking LLM agent that reformulates cross-domain CSI adaptation as a deployment-time decision-making problem, and achieves the best target-domain performance across all splits and improves the average Macro-F1 by about 16\% compared to the strongest baseline method.
