Embodiment Construction
[0026] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.
[0027] The present invention proposes a robust federated learning algorithm based on partial parameter aggregation. First, the server defines a unified upload ratio for each client, and distributes it to the client together with the global model. After calculating the update of the local model, the client selects parameters in the model that meet the upload ratio, which effectively reduces the model information uploaded by malicious clients, but still ensures the correct convergence of the global model. Then, based on homomorphic encryption, the present invention designs encrypted calculations for some of the models uploaded by the client, so that the server can still only obtain the aggregated results of the model parameters, but cann...
