新的HOPE方法解决了异质图节点分类问题

研究人员推出了一种新方法HOPE,用于处理具有异质性的图的开放集节点分类。异质性意味着相连的节点不一定共享相同的标签。该方法解决了现有方法在同质性假设下的局限性,这种假设在真实世界的异质图数据中可能导致表示交织不清以及对未知类别的不可靠拒绝。HOPE采用结构增强的特征初始化和可信赖的邻域聚合机制来更好地处理图结构和过滤噪声邻居,同时采用异质性引导的伪外插策略,通过在模糊区域附近创建合成代理来增强对未知类别的拒绝能力。实验表明,HOPE在有效性、鲁棒性和效率方面均优于当前最先进的模型。 AI

影响 这项研究为复杂、真实世界的图结构中的节点分类提供了一种更鲁棒的方法,有可能改进依赖图分析的应用。
