Graph Neural Network explanations lack canonicality due to input symmetries

作者 PulseAugur 编辑部 · [1 个来源] ·

一篇新研究论文探讨了解释图神经网络（GNN）中的一个根本性问题，特别是它们的解释如何因输入对称性而变得非规范化。研究强调，基于梯度的GNN解释器会为化学等价的原子分配相同的归因分数，但最终报告的解释，例如top-k边，可以根据数组排序任意偏向其中一个。这种任意性是一种结构性障碍，对于像Mutagenicity这样存在常见对称性的数据集尤其成问题。 AI

影响 突出了图神经网络可解释性中的一个根本性局限，可能影响其在分子分析解释中的信任度和可靠性。
