Title:
DATA PROCESSING METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/067779
Kind Code:
A1
Abstract:
A data processing method, which can be applied to the field of artificial intelligence. The method comprises: acquiring first log data of a user and second log data thereof, wherein the first log data comprises first attribute information of a first article, the second log data comprises second attribute information of a second article, and the occurrence time of the first log data is earlier than that of the second log data; processing, by means of a first encoder, a first embedding corresponding to the first attribute information, so as to obtain a first feature representation, and processing, by means a second encoder, a second embedding corresponding to the second attribute information, so as to obtain a second feature representation, wherein the difference between the first feature representation and the second embedding and the difference between the second feature representation and the first embedding are used for constructing a loss; and updating the first encoder and the second encoder according to the loss. The present application can improve the prediction precision of a model.
