English(EN) Understanding Truncated Positional Encodings for Graph Neural Networks

图神经网络的截断位置编码:理论与实验分析

一篇新的研究论文探讨了图神经网络(GNNs)中使用的截断位置编码(PEs)的理论特性。研究表明,虽然完整的谱和基于游走的PEs具有同等的表达能力,但由于复杂性限制而在实践中常用的截断版本却存在显著差异。研究证明,截断的谱PEs的威力不如之前认为的那么大,并且在真实世界数据集上,不同截断PEs的组合表现最佳。 AI

影响 这项研究阐明了GNNs中常用截断位置编码的表达能力,可能有助于更有效的模型设计。
