This invention proposes a long-tail federated learning method and apparatus based on gradient cleanup and residual learning. The method includes: the server selecting clients and distributing global parameters; each client performing local training based on the global parameters to obtain updated local shared parameters, which are then uploaded to the server. During training, the task gradient and the balanced alignment gradient are calculated, and the task gradient is cleaned by projection to remove components opposite to the balanced alignment gradient, resulting in a cleaned gradient. The server aggregates the local shared parameters uploaded by each client to obtain global shared parameters and determines whether the current number of communication rounds has reached a preset limit. If so, the global shared parameters are distributed to all clients for personalized training to obtain client-specific models. During personalized training on each client, global branches and personalized branches are used to improve the long-tail category recognition rate.
