Abstract
A method for training a neural network model includes: at each first member device, obtaining predicted label data according to a first neural network submodel of the first neural network submodel by using private data for model training, and determining model update information of the first neural network submodel according to the predicted label data and real label data; providing, by each first member device, the model update information of the first neural network submodel and local sample distribution information to a second member device; at the second member device, performing neural network model reconstruction, determining an overall sample probability distribution, and allocating a reconstructed neural network model and the overall sample probability distribution to each first member device; and updating the first neural network submodel at each first member device according to a local sample probability distribution, the reconstructed neural network model, and the overall sample probability distribution.
