專利摘要(中)
本發明提出一種基於聯邦學習的模型訓練方法，適用於中央伺服器，方法包括從多個裝置分別接收多個第一模型參數組；計算多個裝置中的第一裝置對應的多個第一模型參數組的其中之一與多個裝置中的至少一其他裝置對應的多個第一模型參數組的至少其中之一之間的至少一第一距離；根據至少一第一距離，計算第一裝置對應的至少一第一權重；根據第一權重，計算第一模型參數組的加權平均，以得到第一裝置對應的第二模型參數組；以及發送第一裝置對應的第二模型參數組至第一裝置。此外，使用上述方法的系統亦被提出。

專利摘要(英)
A method for implementing model training based on federated learning is provided. The method includes: receiving multiple first model parameter sets respectively from multiple devices; calculating at least one first distance between one of the first model parameter sets corresponding to a first device among the multiple devices and at least one of the first model parameter sets corresponding to at least one other device among the multiple devices; calculating at least one first weight corresponding to the first device based on the at least one first distance; calculating a weighted average of the first model parameter sets based on the at least one first weight to obtain a second model parameter set corresponding to the first device; and sending the second model parameter set corresponding to the first device to the first device. In addition, a system using the method is also provided.
