| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary A new dynamic graph convolutional network (DGCN) model is proposed, which combines spatial and temporal information from dynamic graphs. The existing DGCN models are mainly composed of static GCNs and sequence modules, which separate spatiotemporal information and fail to capture complex temporal patterns. This study addresses this issue by introducing a spatial-temporal graph convolutional network with diversified transformation (STGCNDT). The STGCNDT includes three aspects: constructing a unified graph tensor convolutional network using tensor M-products; introducing three transformation schemes to model complex temporal patterns; and constructing an ensemble of diversified transformation schemes. Experimental results on four dynamic graphs from communication networks show that the proposed STGCNDT outperforms state-of-the-art models in link weight estimation tasks due to its ability to capture complex temporal patterns. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary This paper creates a new way to understand changing relationships between things. Dynamic graphs are used to describe these changes, but current methods can’t handle this information very well. The study proposes a new method that combines spatial and temporal information from dynamic graphs, which helps to better understand the changing relationships. |
