English(EN) LLM-Enhanced Self-Evolving Reinforcement Learning for Multi-Step E-Commerce Payment Fraud Risk Detection

LLM增强强化学习用于电子商务欺诈检测 · 2篇论文

两篇研究论文探讨了使用大型语言模型(LLM)来增强强化学习(RL)在电子商务支付欺诈检测中的应用。第一篇论文将欺诈检测构建为一个多步马尔可夫决策过程,并使用LLM来优化奖励函数,从而提高了准确性并展示了零样本能力。第二篇论文通过采用双流LLM引导的奖励设计,解决了欺诈检测中的拒绝推断问题,该设计考虑了被遗留系统阻止的交易,并在精度上显著优于先前的方法。 AI

影响 LLM正被整合到强化学习框架中,以提高欺诈检测的准确性并应对复杂的数据挑战。
