Document Type and Number:
WIPO Patent Application WO/2022/126916
Kind Code:
A1
Abstract:
The present application relates to artificial intelligence, and discloses a product recommendation method, a system, a computer device and a storage medium. The method comprises: a server side receives parameter data; a server obtains a product factor matrix and parameters after initialization, and sends the product factor matrix parameters and the parameter data to multiple clients; the clients update a user factor matrix accordingly, calculate weighted differences and normalized constants by using a q-FedAvg algorithm, and return the weighted differences and normalized constants to the server; the server updates the product factor matrix parameters by using the product factor matrix parameters, the weighted differences and the normalized constants; the server determines a target product factor matrix according to the updated product factor matrix parameters, and sends the target product factor matrix to a target client; and the target client uses the target product factor matrix and the updated user factor matrix to calculate predicted score values and recommend the first N products having a high ranking to a user. The present application improves the fitting degree between recommended products and users while protecting user data from leakage.
