WebJul 1, 2024 · Graph neural networks have been widely used on modeling graph data, achieving impressive results on node classification and link prediction tasks. Yet, obtaining an accurate representation for a graph further requires a pooling function that maps a set of node representations into a compact form. Webany nodes in the neighbourhood. Based on the node features and interaction graphs, we propose a novel Graph-masked Transformer (GMT) architecture, which can flexibly involve structural priors via a masking mechanism. Specifically, in each self-attention layer of GMT, we assign each interaction graph to different heads, and use
WebNodeFormer is flexible for handling new unseen nodes in testing and as well as predictive tasks without input graphs, e.g., image and text classification. It can also be used for interpretability analysis with the latent interactions among data points explicitly estimated. Structures of the Codes WebDec 29, 2024 · We set the depth of the ego-graphs to be 2, i.e., the nodes in the ego-graphs are within the 2-hop neighborhood. The number of neighbors to sample for each node is tuned from 1 to 10. For each ego-graph, we randomly mask a certain portion of nodes according to the mask ratio, and reconstruct the features of the masked nodes.
