English(EN) When Are Experts Misrouted? Counterfactual Routing Analysis in Mixture-of-Experts Language Models

研究发现 MoE 模型在复杂推理任务上错误路由 token

研究人员发现混合专家(MoE)语言模型中存在一个重大问题,即路由机制(将 token 指向特定专家)经常选择次优路径。虽然标准路由器在置信度高的 token 上表现良好,但在复杂推理任务上却无法识别出性能更好的路径。这种错误路由存在于包括 Qwen3、GPT-OSS、DeepSeek-V2 和 OLMoE 在内的几款主流 MoE 模型中。研究表明,即使对路由器进行微小的更新,而不改变专家本身,也能提高在具有挑战性的数学和推理基准测试上的性能,这表明路由效率是关键瓶颈。 AI

影响 识别出 MoE 路由中的一个关键缺陷,该缺陷阻碍了推理能力,并表明有针对性的路由器改进可以提高复杂任务的性能。

    专家何时会被错误路由?混合专家语言模型中的反事实路由分析

    Mixture-of-Experts (MoE) language models route each token to a small subset of experts, but whether the routes selected by a trained top-$k$ router are good ones is rarely evaluated directly. Holding the model fixed, we compare each standard route against sampled equal-compute al…
