Cross-domain contrastive learning

WebApr 13, 2024 · (1) In the encoding step, CLCDR aims to model the user and item representations of the source and target domains respectively with a newly proposed contrastive loss. In this way, the interactions between users and items can be represented by the distances in the latent space. WebThe within- and cross-domain graph contrastive learning is carried out by optimizing an objective function, which combines source classifier and target classifier loss, domain-specific contrastive loss, and cross-domain contrastive loss. As a result, feature learning from graphs is facilitated using knowledge transferred between graphs.
