基于视图解耦与反事实增强的公平图学习OA

Fair graph learning via view disentanglement and counterfactual augmentation

中文摘要英文摘要

图神经网络(GNN)因其对图结构数据的强大建模能力,已在诸多真实场景中得到广泛应用.近年来的研究表明,GNNs 可能会继承并放大训练数据中固有的偏差,从而使得由敏感属性定义的特定群体受到不公平对待.为缓解图数据中的偏差问题,本文提出一种基于视图解耦与反事实增强的公平图学习框架 FairDC,分别针对特征偏差和结构偏差进行去偏.该框架首先将原始图数据解耦为特征视图和结构视图,然后在此基础上引入反事实视图,最后采用多视图融合策略学习公平节点表示.在多个基准数据集上的实验结果表明,FairDC 在保持预测性能基本稳定的同时,相比于最新基线方法 DAB,公平性指标人口平等(DP)和机会均等(EO)分别下降 32%和 36%,验证了其在效用与公平性之间的有效权衡能力.

Graph Neural Network(GNN)have been widely applied in numerous real-world scenarios due to their powerful modeling capabilities for graph-structured data.Recent studies indicate that GNN may inherit and amplify biases inherent in training data,leading to unfair treatment of specific groups defined by sensitive attributes.To mitigate bias in graph data,this paper proposes FairDC,a fair graph learning framework based on view decoupling and counterfactual augmentation,which addresses feature bias and structural bias separately.The framework first decouples raw graph data into feature views and structural views,then introduces counterfactual views.Finally,a multi-view fusion strategy is employed to learn fair node representations.Experimental results on multiple benchmark datasets demonstrate that FairDC maintains stable prediction performance while reducing fairness metrics DP and EO by 32%and 36%,respectively,compared with the state-of-the-art baseline DAB.This validates the proposed method's effective trade-off between utility and fairness.
