Multi-View Graph Convolutional Network for Multimedia Recommendation是南邮研究人员发表在MM 23的多模态推荐的工作,同其他推荐场景一样,多模态推荐模型也基本上以GCN为主流,本文作者提出了Multi-View GCN模型,也就是多视角 GCN 模型,简单说就是各个模态和 id 向量如何做融合。作者设计的出发点有两个,一是模态数据...

最后,添加了额外的特征相似视图来补充节点特征信息。通过三个单独的图卷积编码器,可以学习到三个表示矩阵。因此,从模型图上看,其实比较重要的是三个邻接矩阵的计算。而GCNs则是使用了两层的GCN,并且这里的GCN之间并没有共享。那么在这部分重点介绍不同类型的邻接矩阵的介绍。

Multimedia recommendation has received much attention in recent years. It models user preferences based on both behavior information and item multimodal information. Though current GCN-based methods achieve notable success, they suffer from two limitations: (1) Modality noise contamination to the item re...
We leverage a 2-layer GCN as the encoder for each metapath-induced view. The parameters are initialized via Xavier initialization43and we apply Adam as the optimizer44. We perform grid search to tune the learning rate from 5e-4 to 5e-3, the value of temperature from 0.2 to 0.8, the co...
