Summary: | The invention provides a federal learning client selection method and system for long-tail data, and the method comprises the steps: calculating the contribution score of each client, and selecting the first N clients with the contribution scores ranked from high to low; local models uploaded by the first N clients are received, one or more clients meeting the uploading time delay requirement serve as selected clients, and the local models are obtained by conducting long-tail data training on a first global model issued by a server through the clients; aggregating the local models uploaded by all the selected clients, and updating the first global model according to the aggregated models to obtain a second global model; according to the method, the influence of long-tail data and a wireless fading channel on the performance of the federated learning model can be reduced, and the universality and robustness of the model are improved.
