Robust Graph Neural Network
Robust Graph Neural Networks (GNNs) aim to improve the resilience of GNN models against various forms of noise and adversarial attacks, which can significantly degrade their performance on graph-structured data. Current research focuses on developing novel architectures and algorithms, such as those employing weighted Laplacian matrices, contrastive learning, and adaptive message passing schemes, to enhance robustness against structural attacks, noisy edges, and model mismatch during training and testing. This work is crucial for ensuring the reliability and trustworthiness of GNNs in real-world applications, particularly in safety-critical domains where adversarial manipulation could have significant consequences. The development of robust GNNs is driving advancements in both theoretical understanding of GNN vulnerabilities and practical improvements in their performance across diverse applications.
