GNN在金融模型中存在时间泄露问题;发布新基准

研究人员发现,在应用于金融交易数据时,消息传递图神经网络(GNN)普遍存在时间泄露问题。这种泄露发生是因为标准的训练分割可能会将模型暴露于未来信息,从而导致性能指标虚高。为了解决这个问题,发布了一个新的基准数据集SynthFin-AML v10.0,该数据集通过三快照架构强制执行严格的因果边界,确保模型仅使用过去的数据进行训练。在该严格基准上进行评估时,一个经过调优的LightGBM模型表现与GraphSAGE GNN相当,这表明在反洗钱任务中,如果没有大量的边特征密度,GNN可能并不总是比传统的表格方法具有显著优势。 AI

影响 强调了GNN在动态图任务中性能可能被高估的问题,并强调了严格评估方法的必要性。
