Embodiment Construction
[0050] The solutions provided in this specification will be described below in conjunction with the accompanying drawings.
[0051] As mentioned above, when multiple data parties jointly train the machine learning model (or predictive model), they need to ensure the privacy and security of their own data and prevent the leakage of private data. In a collaborative training method proposed, a neutral global server (hereinafter referred to as the server) is set up, and a communication connection is established between each data party and the server, so that the data of all parties can achieve value fusion with the help of the server. In this way, There is no need for direct communication between the various data parties, thereby ensuring the privacy and security of the data of all parties to a certain extent.
[0052] specifically, figure 1 A communication architecture diagram showing a collaborative training machine learning model according to an implementation manner, such as ...
