Jianjun Yin · Internet Technology Letters · 2025
ABSTRACT Cloud‐assisted physical education teaching is an important direction for the development of smart education. However, the data processing and transmission of videos severely restrict the real‐time performance of action analysis. To this end, this paper proposes an efficient edge cloud‐assisted student movement recognition framework based on the graph convolutional network and human skeleton data. On the edge server, we use the YOLO‐pose algorithm to generate robust human skeleton sequences and design an improved spatial–temporal dual stream graph convolutional neural network with an early fusion structure, which introduces the node weight module and the dynamic graph module to exploit long‐distance dependency relationships of nodes. In the cloud server, we use a federated learning framework based on the density clustering mechanism to collaboratively train and aggregate parameters of models scattered across edge nodes. The experimental results show that our proposed model achieves excellent recognition accuracy on the self‐built sports action dataset, providing an effective solution for intelligent and real‐time feedback in outdoor sports teaching.
