- TLDR:This work replaces the Jensen-Shannon Divergence routing with C_struct, a structural proxy that measures mass at Vertical-Slash compatible positions and reproduces JSD's routing decisions while eliminating both the pooled matmul and subsequent KL divergence overhead.

- TLDR中文:本文用 C_struct 替代 Jensen-Shannon Divergence 路由:C_struct 是一种结构化代理,通过度量 Vertical-Slash 兼容位置上的 mass 来复现 JSD 的路由决策,同时消除池化 matmul 与后续 KL 散度开销。
