STF-AL: spatiotemporal-frequency feature representation and adversarial learning for sensor-based cross-domain human activity recognition

STF-AL, a sensor-based cross-domain HAR framework that combines spatiotemporal-frequency domain representation learning with adversarial domain adaptation, achieves superior or competitive performance in multiple cross-domain recognition tasks, indicating its effectiveness under the evaluated cross-domain HAR settings.
