Abstract

The present invention relates to the field of financial technology, and in particular to an information recommendation method and device. The method includes: a first server obtains an information recommendation request sent by a third server; the first server determines the information according to a first information recommendation model The first predicted value of the recommendation request; the first information recommendation model is determined by the first server and the second server according to federated learning; the user data of the first server and the second server are not shared; The first server determines the query gain value of the information recommendation request according to the query prediction model; if the first server determines that the query gain value is less than a preset threshold, then according to the first prediction value, the 3. The server returns a response to the information recommendation request.

Description

technical field [0001] The present invention relates to the field of financial technology, in particular to an information recommendation method and device. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into financial technology (Finteh). Federated learning technology is no exception. However, due to the security and real-time requirements of the financial industry, It also places higher demands on technology. [0003] In the current federated learning technology, any participant in the federated learning can improve the accuracy of the prediction by querying the prediction results of one (or more) other participants. However, during the application process, querying data between participants in federated learning may lead to low recommendation efficiency and increase costs. Contents of the invention [0004] Embodiments...
