Abstract

The embodiment of the invention provides a model joint training method and device based on privacy protection. In the joint training process, under the condition that the target number is greater thanor equal to a preset target iteration round, the number of gradients for joint training is adjusted based on the target number, the server determines the number (i.e., the target number) of gradientsneeding to be sent to the server by the terminal in the next round or several rounds of iteration, so that the terminal participating in joint training does not need to upload all the obtained gradients to the server in the whole joint training process.

Description

Technical field[0001]The embodiments of this specification relate to the field of data security technology, specifically, to a joint training method and device of a model.Background technique[0002]In order to solve the problem of data islands, the joint training of models through the cooperation of multiple terminals has gradually attracted the attention of the industry.[0003]The number of terminals (which may include a server and at least one terminal) involved in the joint training process is not unique. In the process of joint training, more than one data transmission may be required between at least two terminals participating in the joint training. It can be seen that joint training is accompanied by high communication overhead and hidden dangers in data security to a certain extent. In some network environments and computing environments, this phenomenon is more obvious.Summary of the invention[0004]The embodiments of this specification provide a joint training method and devi...
