Multi-View Dynamic Heterogeneous Information Network Embedding

no code implementations12 Nov 2020 Zhenghao Zhang, Jianbin Huang, Qinglin Tan

To tackle above challenges, we propose a novel framework for incorporating temporal information into HIN embedding, denoted as Multi-View Dynamic HIN Embedding (MDHNE), which can efficiently preserve evolution patterns of implicit relationships from different views in updating node representations over time.
