Title:
DATA PROCESSING METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/012360
Kind Code:
A1
Abstract:
A data processing method, which can be applied to the field of artificial intelligence. The method comprises: predicting, according to a first training sample, first operation information of a user for an item by means of a first recommendation model, wherein the first operation information and second operation information are used for determining a first loss, the second operation information comprises information obtained according to an operation log of the user, and the first loss is used for updating the first recommendation model; and predicting, according to a second training sample, third operation information and fourth operation information of the user for the item by means of a second recommendation model and the updated first recommendation model, respectively, wherein the third operation information and the fourth operation information are used for determining a second loss, and the first recommendation model and the second recommendation model are sorting models in different stages of a multi-stage cascade recommendation system. In the present application, a joint training mode is used, such that a model in each stage focuses on the fitting of data of the respective stage thereof, and upstream and downstream stages are also used to assist with training, thereby improving the prediction effect.
