Typical Graph Neural Networks (GNNs) have achieved noticeable performance in node classification tasks with the strategy of neighbor aggregation, which benefits from homophily assumption graphs (nodes same class tend to be connected). However, many models degrades tensely when data heterophilic. Therefore, we need optimize aggregation deal these two different types graphs. In this paper, propose a Path Based Attention Network (PBGAN) address issue. It utilizes structure and path information...
