新“回声室效应”在图神经网络中被识别

研究人员在图神经网络(GNNs)中识别出一种新的故障模式,称为“回声室效应”,这与已知的过平滑问题不同。当社区内部的表示迅速崩溃,而社区间的区分度仍然存在时,就会发生这种效应,导致社区内部的表示无法区分。为了量化这一点,开发了一种名为回声室指数(ECI)的新指标。提出的解决方案是社区感知分裂传播(CASP),这是一个轻量级的插件,旨在分离社区内部和社区间的聚合,从而提高GNN在各种设置下的性能。 AI

影响 为GNN引入了一种新的故障模式和指标,有可能提高模型在社区结构化数据中的鲁棒性和性能。

    不仅仅是过平滑:检测图神经网络中的回声室效应

    arXiv:2609.06521v1 Announce Type: new Abstract: Oversmoothing is a well-known failure mode of Graph Neural Networks (GNNs). However, most existing diagnostics rely on global aggregation measures that fail to capture the heterogeneous dynamics of message passing. Real-world graphs…
