  Recent WiFi-based fall detection systems have drawn much attention due to
their advantages over other sensory systems. Various implementations have
achieved impressive progress in performance, thanks to machine learning and
deep learning techniques. However, many of such high accuracy systems have low
reliability as they fail to achieve robustness in unseen environments. To
address that, this paper investigates a method of generalization through
adversarial data augmentation. Our results show a slight improvement in deep
learning-systems in unseen domains, though the performance is not significant.
