# MoE模型幻觉问题获新解：反事实路由激活休眠专家

arXiv论文提出反事实路由方法，解决MoE模型处理长尾知识时的幻觉问题。研究发现静态Top-K路由导致专家利用率不足，通过反事实查询激活休眠专家可减少37%的幻觉率。该方法在WikiText和MMLU测试中表现优于传统路由策略。

## English Version

**Counterfactual Routing Activates Dormant Experts to Fix MoE Hallucinations**

An arXiv paper proposes counterfactual routing to fix MoE hallucination on long-tail knowledge. The method activates dormant experts by simulating counterfactual queries, reducing hallucinations by 37%. It outperforms traditional routing on WikiText and MMLU benchmarks.
