Papers with RL optimizes risk detection
LLM-Enhanced Self-Evolving Reinforcement Learning for Multi-Step E-Commerce Payment Fraud Risk Detection (2025.acl-industry)
Copied to clipboard
| Challenge: | e-commerce payment fraud detection is a new area for reinforcement learning (RL) and Large Language Models (LLMs). |
| Approach: | They propose to integrate reinforcement learning (RL) with Large Language Models (LLMs) by framing transaction risk as a multi-step Markov Decision Process (MDP), RL optimizes risk detection across multiple payment stages. |
| Outcome: | The proposed approach improves fraud detection accuracy and demonstrates zero-shot capability. |
