Gravity-GNN: Deep Reinforcement Learning Guided Space Gravity-based Graph Neural Network
Graph Neural Networks (GNNs) are powerful for graph data, but their reliance on neighborhood aggregation can lead to inefficiencies or invalid embeddings due to irrelevant information. Gravity-GNN addresses this with two innovations: 'node gravity' (a novel similarity measure inspired by physics, combining local topology and node features) and Deep Reinforcement Learning (DRL) for adaptive neighbor selection. Experiments show Gravity-GNN outperforms state-of-the-art methods in node classification accuracy and demonstrates greater robustness against disturbances, especially on noisy datasets like ACM.

Robustness in Noisy Graph Data (ACM Dataset)
Gravity-GNN demonstrated remarkable robustness against randomly introduced noisy edges in the ACM dataset. Traditional GCNs suffer from dilution of information, while Gravity-GNN's 'node gravity' measure effectively captures node features and local topology, making it resilient to disturbances. This is crucial for real-world applications with imperfect data. For example, at a 5% perturbation rate, Gravity-GNN maintained superior accuracy compared to other methods.
The resilience is attributed to the node gravity measure, which effectively captures both node features and local topology, along with the DRL-based neighbor selection optimizer.
