新的ECoG框架增强了欺诈检测在面对未知场景时的鲁棒性

作者 PulseAugur 编辑部 · [1 个来源] ·

研究人员开发了ECoG，一个新颖的生成式框架，旨在提高欺诈检测模型在面对场景级分布偏移时的鲁棒性。该框架在训练过程中结合了证据跨度监督和推理-标签一致性目标。与标准训练方法相比，ECoG在具有挑战性的分布外实例上将Macro-F1分数提高了3.22个百分点，并将参考证据跨度的token级重叠度提高了8.38个百分点。 AI

影响 通过提高对新攻击场景的泛化能力，增强了AI模型在检测复杂欺诈行为时的可靠性。

    arXiv:2608.21043v1 Announce Type: new Abstract: Conventional in-distribution evaluation can overestimate robustness when training and test data share recurring task-specific patterns or surface cues. This risk is especially relevant in social-engineering fraud detection, where at…
