Compared with state-of-the-art models, the experimental results proved the superior effectiveness of the proposed Hop-aware Supervision Graph Attention Networks (HopGAT) model. ... This study first proposes a hop-aware attention supervision mechanism for the node classification task. ... Experiments In this section, we evaluate the performance of the proposed hop-aware attention supervision model to address the node classification task on a sparsely labeled graph network. ...arXiv:2004.04333v1 fatcat:mcujini44jbhzfo3wrw7ivl2sq
