New MOSS framework enhances recommender system diversity

Researchers have developed a new framework called MOSS to improve the diversity of recommender systems. Current systems often prioritize accuracy, leading to a narrow range of recommendations. MOSS addresses this by decoupling multimodal signals and shaping both semantic and structural representations. It uses a module for disentangling multimodal content and another for category-aware semantic feature extraction. Additionally, it incorporates dual-graph propagation to prevent representation collapse and entropy-based regularization to promote balanced category exposure, leading to better accuracy-diversity trade-offs.
