[0067] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0068] The existing technology is aimed at the problem of cold-start users in the target domain when there are anchor users in the two domains, and cannot perform cross-domain recommendation in the case of multiple auxiliary domains. The present invention has a cross-domain recommendation method with multiple auxiliary domains, which alleviates the problem of unsatisfactory recommendation effect caused by the poor prediction accuracy of the traditional single auxiliary domain matrix decomposition model, improves the recommendation effect of the recommendation system, and has more versatility.
