| Abstract: |
Graph Neural Networks (GNNs) have drawn increasing attention in recent years and achieved outstanding success in many scenarios and tasks. However, existing methods indicate that the performance of representation learning drops dramatically as GNNs deepen, which is attributed to over-smoothing representation. To handle the above issue, we propose an adaptive receptive field graph neural network (ADRP-GNN) that aggregates information by adaptively expanding receptive fields with a monolayer graph convolution layer, avoiding deepening to result in the over-smoothing issue. Specifically, we first present a Multi-hop Graph Convolution Network (MuGC) that captures the information of the nodes and their multi-hop neighbors with only one layer, preventing frequent passing messages between nodes from the over-smoothing issue. Then, we design a Meta Learner that realizes the adaptive receptive field for each node to select related neighbor information. Finally, a Backbone Network is employed to enhance the architecture's learning ability. In addition, our architecture adaptively generates receptive fields instead of handcrafting stacked layers, which can integrate existing GNN frameworks to fit various scenarios. Extensive experiments indicate that our architecture is effective for the over-smoothing issue and improves accuracy by 0.52% to 6.88% compared to state-of-the-art methods on node classification tasks on eight datasets. • A monolayer graph convolution (MuGC) captures multi-hop graph structure information. • Meta Learner realizes the adaptive receptive field for each node. • Our framework, ADRP-GNN, relieves the over-smoothing issue. • Extensive experiments are conducted to evaluate ADRP-GNN on 8 real-world datasets.
