Abstract
A data processing method and apparatus, an electronic device, and a storage medium acquire label residual values determined for respective data samples, each label residual value being used for representing a degree of deviation between a real label of a corresponding data sample and a label predicted by a target model; perform residual decomposition on the respective data samples based on respective label residual values to obtain model parameter correction amounts corresponding to the respective data samples; and send the model parameter correction amounts to a data receiver. The data receiver reconstructs model parameter information of the target model based on the model parameter correction amounts. Perturbing residuals through residual decomposition enables a data sender to protect the real labels owned thereby, while the data sender can send necessary correction information to the data receiver to reconstruct accurate model parameter information to ensure the model training performance.
