新方法解决图神经网络（GNN）的置信度不足问题

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了一种新方法来解决图神经网络（GNN）的置信度不足问题。该方法建立了一个理论框架，将模型置信度与最后一层的类质心和节点级校准联系起来。通过减少最后一层参数的权重衰减，该方法在理论上缓解了类质心级别的 GNN 置信度不足，而节点级校准则通过鼓励测试节点与其预测的类原型对齐来进一步完善这一点。 AI

影响 通过解决置信度不足问题，提高了 GNN 预测的可靠性，有可能增强基于图的任务的性能。

    Understanding and Mitigating Under-Confidence in GNNs from the Final Layer

    arXiv:2505.11335v5 Announce Type: replace Abstract: Graph Neural Networks (GNNs) have demonstrated remarkable effectiveness on graph-based tasks. However, their predictive confidence is often miscalibrated, typically exhibiting under-confidence, which harms the reliability of the…
