DivCDSR: A Model-Agnostic Framework for Diverse Cross-Domain Sequential Recommendation

DivCDSR is proposed, a novel model-agnostic framework designed to enhance diversity in CDSR that introduces a dual-prototype semantic constraint mechanism that mitigates the homogenization trap via intra-domain clustering with orthogonalization and inter-domain separation and devise a dual-guided diffusion module that...

DivCDSR: A Model-Agnostic Framework for Diverse Cross-Domain Sequential Recommendation

While Cross-Domain Sequential Recommendation (CDSR) has proven effective in mitigating data sparsity and enhancing accuracy, its impact on recommendation diversity remains largely unexplored. We are the first to reveal a counterintuitive phenomenon: while CDSR improves accuracy, it often comes at the cost of diversity,...
