DREAM: Dual-Standard Semantic Homogeneity with Dynamic Optimization for Graph Learning with Label Noise

  • 通过动态优化框架,根据节点关系重新评估标签可靠性。
  • 采用双标准锚点选择,结合邻近性和图结构提升判断准确性。
  • 理论严谨,在6个数据集上对3类噪声均表现优于现有方法。

图神经网络广泛应用于各类图机器学习任务,但现实场景中标签可靠性难以保证。现有方法常无法区分可靠与不可靠节点,且忽略图结构中的关系信息。为此,本文提出双标准语义同质性动态优化方法(DREAM),通过关系感知的动态优化框架,在训练过程中迭代重评每个节点的标签可靠性。该方法基于节点邻近性和图拓扑双重标准选取锚点,计算目标节点与锚点间的语义同质性,作为优化指导。我们还提供了严格的理论分析。在六个跨领域图数据集上,针对三类标签噪声进行的大量实验表明,DREAM显著优于现有基线方法。

原文摘要 · Abstract (English)

Graph neural networks (GNNs) have been widely used in various graph machine learning scenarios. Existing literature primarily assumes well-annotated training graphs, while the reliability of labels is not guaranteed in real-world scenarios. Recently, efforts have been made to address the problem of graph learning with label noise. However, existing methods often (i) struggle to distinguish between reliable and unreliable nodes, and (ii) overlook the relational information embedded in the graph topology. To tackle this problem, this paper proposes a novel method, Dual-Standard Semantic Homogeneity with Dynamic Optimization (DREAM), for reliable, relation-informed optimization on graphs with label noise. Specifically, we design a relation-informed dynamic optimization framework that iteratively reevaluates the reliability of each labeled node in the graph during the optimization process according to the relation of the target node and other nodes. To measure this relation comprehensively, we propose a dual-standard selection strategy that selects a set of anchor nodes based on both node proximity and graph topology. Subsequently, we compute the semantic homogeneity between the target node and the anchor nodes, which serves as guidance for optimization. We also provide a rigorous theoretical analysis to justify the design of DREAM. Extensive experiments are performed on six graph datasets across various domains under three types of graph label noise against competing baselines, and the results demonstrate the effectiveness of the proposed DREAM.
