Wearable Sensor-Based Residual Multifeature Fusion Shrinkage Networks for Human Activity Recognition
Publikováno v:
Sensors, Vol 24, Iss 3, p 758 (2024)
Human activity recognition (HAR) based on wearable sensors has emerged as a low-cost key-enabling technology for applications such as human–computer interaction and healthcare. In wearable sensor-based HAR, deep learning is desired for extracting h
