Abstract

The embodiment of the invention provides a user characterization method and device, electronic equipment and a computer readable medium, and relates to the field of artificial intelligence. The methodcomprises the following steps: based on first feature data of a sample user in a source domain and second feature data of the sample user in a target domain, training a to-be-trained cross-domain feature representation model; and generating first cross-domain feature representation data of the to-be-represented user in the target domain based on third feature data of the to-be-represented user inthe source domain through the trained cross-domain feature representation model. According to the embodiment of the invention, the personalized representation effect of the user with missing target domain features in the target domain can be effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the field of artificial intelligence, and in particular to a user characterization method, device, electronic equipment, and computer-readable medium. Background technique [0002] Product recommendation and product search for cold-start users are important means to increase user activity and increase user volume in modern e-commerce, and are also important references for users' first impressions of e-commerce platforms. However, cold-start users usually lack historical behaviors such as clicking or purchasing products on e-commerce platforms, and user portraits on e-commerce platforms are very sparse. It is difficult to predict cold-start user preferences using traditional machine learning models. Higher accuracy. Thanks to the development of big data platforms, in many e-commerce companies, in addition to the field of product recommendation tasks, there will be other fields. For example, in additi...
