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).

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.
