DATA PROCESSING METHOD, APPARATUS, DEVICE, AND STORAGE MEDIUM

Provided are a data processing method, apparatus, device, and storage medium, executed by a first device in a data processing system, said method comprising: obtaining first sample data of a target operation (401); on the basis of the first sample data, training a first service processing model to obtain a first model parameter of the first service processing model (402); sending the first model parameter to a second device connected to the first device, the second device determining a first fusion parameter, sending the first fusion parameter to another second device, the first fusion parameter being obtained by the second device on the basis of the received first model parameter and a second model parameter determined on its own, the second device being a device other than the first device in the data processing system ( 403 ); obtaining a second fusion parameter, the second fusion parameter comprising model parameters determined by at least three devices in the data processing system ( 404 ); according to the second fusion parameter, determining a target model parameter for the first service processing model ( 405).
