English(EN) Graph Representation Learning via Adaptive Expectile Aggregation

新的ExpectileGCN框架增强了图神经网络

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-28 04:00

研究人员推出了一种新颖的图表示学习框架ExpectileGCN，该框架通过超越简单的均值聚合来增强图神经网络（GNN）。这种新方法包含一个可学习的期望分位数水平，使其能够自适应地捕获图中邻域内更细微的分布信息，这对于异质图尤其有利。ExpectileGCN可以动态调整其聚合行为，范围从最小值到最大值，其中均值聚合是特定实例，并在基准数据集上展示了强大的性能，显示出对特征损坏和结构扰动的改进鲁棒性。 AI

影响为图神经网络引入了一种更鲁棒的聚合方法，有望提高在异质图数据集上的性能。

通过自适应期望分位数聚合实现图表示学习

arXiv:2610.37450v1 Announce Type: new Abstract: Graph neural networks (GNNs) rely critically on neighborhood aggregation, yet conventional mean aggregation may fail to capture class-relevant distributional information, particularly in heterophilic graphs. We propose ExpectileGCN,…
