Network training method and device, action recognition method and device, equipment and storage medium

Abstract

The invention provides a network training method and device, an action recognition method and device, equipment and a computer readable storage medium. The method comprises the following steps: updating model parameters of a pre-training model by utilizing a first sequence data set of a human skeleton point sequence and a visual angle label corresponding to each piece of first sequence data in thefirst sequence data set; initializing model parameters of a human body action recognition model based on the updated model parameters of the pre-trained model; wherein the pre-training model and thehuman body action recognition model have feature extraction networks with the same structure; and updating model parameters of the human body action recognition model by utilizing the second sequencedata set of the human body skeleton point sequence and the action category label corresponding to each second sequence data in the second sequence data set to obtain a trained human body action recognition model. Through the method and the device, the action recognition precision of the human body action recognition model can be improved, the model training time can be reduced, the dependence on strong annotation data can be reduced, and the manual workload is further reduced.
