Background on graph convolutional networks (GCN)
Graph Convolutional Networks (GCNs) have emerged as a powerful technique for learning representations of graph-structured data. They leverage the connectivity patterns encoded in a graph to extract meaningful features for downstream tasks such as node classification and link prediction. GCNs operate by propagating information through the nodes and edges of a graph, which allows them to capture both local and global structural patterns. The underlying intuition is that nodes should have similar representations if they are connected or share similar neighbors. This property is exploited by aggregating information from a node's neighbors and updating the node's representation accordingly. Several variants of GCNs have been proposed, including spectral-based approaches and spatial-based approaches. Spectral-based GCNs utilize the eigendecomposition of the graph Laplacian to define convolutional filters, while spatial-based GCNs directly propagate and aggregate information among neighboring nodes.

By doing so, GDC not only improves the accuracy of predictions but also ensures the consistency and reliability of the results, making it a versatile and robust method for handling noisy and heterogeneous data.
Enhanced modeling of long-range dependencies
Another advantage of GDC is its enhanced modeling of long-range dependencies. Traditional graph convolutions have limitations in capturing long-range dependencies due to the limited receptive field of the convolutional filters. However, GDC addresses this issue by employing graph diffusion, which allows information from distant nodes to be iteratively propagated through the graph. This diffusion process is guided by the Laplacian matrix, which encodes the connectivity information of the graph. By iteratively updating the feature representations based on the diffusion process, GDC effectively captures long-range dependencies and improves the model's ability to understand global patterns in the graph. Consequently, GDC outperforms traditional graph convolutional methods in tasks that heavily rely on long-range dependencies, such as link prediction and node classification.
