Siamese Graph-Based Dynamic Matching for Collaborative Filtering

, which learns user/item embeddings respectively on the siamese homogeneous graphs. The dual dynamic aggregation in graph convolution endows a specific user-item pair with dynamic matching, which is expected to meet the needs of fine-grained filtering and promote the performance of collaborative filtering. Extensive experimental results confirm the collaboration between siamese homogeneous graphs of users and items. It further illustrates the effectiveness of the proposed SGDM in mining homogeneous collaborative signals for embedding learning and collaborative filtering.
