Querying Cohesive Subgraph regarding Span-Constrained Triangles on Temporal Graphs with Dynamic Index Maintenance
Chuhan Hu, Ming Zhong, Lei Li
Recent advances in temporal graph research have redefined traditional static graph concepts such as triangles, motifs, and -cores. Inspired by this, we introduce a novel …
A Survey on Sequential Recommendation
Liwei Pan, Weike Pan, Meiyan Wei +2
Different from most conventional recommendation problems, sequential recommendation focuses on learning users' preferences by exploiting the internal order and dependency among the…
A Unified and Scalable Algorithm Framework of User-Defined Temporal -Core Query
Ming Zhong, Junyong Yang, Yuanyuan Zhu +3
Querying cohesive subgraphs on temporal graphs (e.g., social network, finance network, etc.) with various conditions has attracted intensive research interests recently. In this pa…
GNN4FR: A Lossless GNN-based Federated Recommendation Framework
Guowei Wu, Weike Pan, Zhong Ming
Graph neural networks (GNNs) have gained wide popularity in recommender systems due to their capability to capture higher-order structure information among the nodes of users and i…
