# 研究发现MoE路由机制类似哈夫曼编码：高频token优先分配

一项新研究揭示了混合专家模型（MoE）路由机制的核心原理：路由并非随机选择，而是遵循类似哈夫曼编码的频率-多样性定律。模型会优先将高频token分配给少数专家，低频token则分散至更多专家，从而实现高效计算。该发现为解释MoE模型的工作原理提供了理论基础。

## English Version

**MoE Routing Resembles Huffman Coding: Frequent Tokens Get Priority**

A new study uncovers a fundamental principle in Mixture-of-Experts (MoE) routing: it behaves like Huffman coding. High-frequency tokens are preferentially routed to a few experts, while low-frequency tokens are distributed across more experts, enabling efficient computation. This provides a theoretical foundation for understanding MoE model behavior.
