The application provides a skeleton data action recognition method based on a multi-relation graph convolutional neural network, which extracts high-level features of skeleton data from different scales by considering human natural connection relations, symmetric relations and global cooperation relations, and effectively fuses the high-level features by a relation attention mechanism. In this way, the network pays more attention to key part information in different actions, and does not lose effective information of other parts. In order to solve the overfitting and oversmoothing problems commonly existing in the graph convolutional neural network, the application proposes a new regularization method: Drop-Relation.
