Researchers have developed new deep learning frameworks for human activity recognition using WiFi signals, offering a privacy-preserving alternative to camera-based systems. One approach, WISE-HAR, utilizes an ensemble of five CNN architectures and aggressive data augmentation to achieve 94.87% accuracy in recognizing activities like walking and arm-waving. Another method employs a lightweight Temporal Convolutional Network (TCN) with physics-guided attention mechanisms to efficiently capture motion dynamics from WiFi CSI data, outperforming deeper baselines with reduced computational cost.
