A cross-domain recommendation algorithm combining multi-personalized bridges and self-supervised learning (MS-PTUPCDR) is proposed for users with less project interaction in the target domain in the cross-domain recommendation system. Firstly. a variational bipartite graph encoder is added to the target domain. and a variational inference framework is used to generate potential variab... https://allfixelectricales.shop/product-category/screen-protector/
