WebSep 6, 2024 · The self-attention mechanism was combined with the graph-structured data by Veličković et al. in Graph Attention Networks (GAT). This GAT model calculates the representation of each node in the network by attending to its neighbors, and it uses multi-head attention to further increase the representation capability of the model [ 23 ]. WebTo address the above issues, we propose a Community-based Framework with ATtention mechanism for large-scale Heterogeneous graphs (C-FATH). In order to utilize the entire heterogeneous graph, we directly model on the heterogeneous graph and combine it with homogeneous graphs.
