Abstract
Source and target vectors encode roles of a node in a directed graph as a source and a target role respectively. Source and target query matrices and source and target key matrices are learned based on the directed graph. The source query matrix and the target key matrix are projected and scaled to create a source-target attention matrix and the target query matrix and the source key matrix are projected and scaled to create a target-source attention matrix. The attention matrices are combined to generate a source-target vector-edge encoding and a target-source vector-edge encoding, and are also biased and gated to generate a modified source-target attention matrix and a modified target-source attention matrix, respectively. Source encodings and target encodings are generated using the modified attention matrices. A classification task is performed with respect to the obtained directed graph based on the generated source encodings and the generated target encodings.
