English(EN) Beyond State Capacity: Why Retrieval Breaks in Mamba

Mamba 模型在检索方面遇到困难,原因在于相关性信号延迟,而非仅仅是状态容量问题

一篇新的 arXiv 论文挑战了 Mamba 模型在上下文检索方面表现不如 Transformer 是由于状态容量限制的假设。研究人员发现,即使查询先于上下文出现,Mamba 模型也落后于 Transformer。这是因为检索的相关性信号是随着模型深度逐渐出现的,而 Mamba 的选择门要到几层之后才能与该信号对齐,从而阻碍了成功的检索,这超出了状态容量问题。 AI

影响 突出了 Mamba 架构在检索任务方面的一个潜在瓶颈,表明需要进一步研究才能获得有竞争力的性能。

    超越国家能力:为什么 Mamba 中的检索会失效

    arXiv:2610.19709v1 Announce Type: new Abstract: Mamba models underperform Transformers on in-context retrieval. This gap is usually attributed to Mamba's fixed-size recurrent state, which loses information as the context grows. We challenge this assumption by focusing on query-fi…
