Enhancing Robustness and Generalization Capability for Multimodal Recommender Systems via Sharpness-Aware Minimization

Jinfeng Xu, Zheyu Chen, Jinze Li, Shuo Yang, Wei Wang, Xiping Hu, Raymond Chi-Wing Wong, Edith Ngai

Paper

  • We propose a sharpness-aware minimization strategy focused on batch data (BSAM), which effectively enhances the robustness and generalization capability of multimodal recommender systems without requiring extensive hyper-parameter tuning. Furthermore, we introduce a mixed loss variant strategy (BSAM+), which accelerates convergence and achieves remarkable performance improvement.

Squeeze and Excitation: A Weighted Graph Contrastive Learning for Collaborative Filtering

Zheyu Chen, Jinfeng Xu, Yutong Wei, Ziyue Peng

Paper

  • A critical problem in existing GCL-based models is the irrational allocation of feature attention. This problem limits the model’s ability to effectively leverage crucial features, resulting in suboptimal performance. To address this, we propose a Weighted Graph Contrastive Learning framework (WeightedGCL). [Code]

COHESION: Composite Graph Convolutional Network with Dual-Stage Fusion for Multimodal Recommendation

Jinfeng Xu, Zheyu Chen, Wei Wang, Xiping Hu, Sang-Wook Kim, Edith Ngai

Paper

  • Modality fusion and representation learning were considered as two independent processes in previous work. In this paper, we reveal that these two processes are complementary and can support each other. Specifically, powerful representation learning enhances modality fusion, while effective fusion improves representation quality. Stemming from these two processes, we introduce a COmposite grapH convolutional nEtwork with dual-stage fuSION for the multimodal recommendation, named COHESION. [Code]
