# 新研究：证据前置+压力自适应预算，缓解RAG瓶颈

一项新研究针对检索增强生成（RAG）系统的效率瓶颈提出优化方案。现有方法多聚焦于优化下游LLM生成（如上下文压缩），但忽略了RAG端到端系统中瓶颈可能在上游检索环节。该方法通过“证据前置”（Evidence Frontloading）提前加载关键证据，并结合“压力自适应预算”（Pressure-Adaptive Budgeting）动态分配资源，有效缓解了检索与生成之间的效率瓶颈。

## English Version

**New Study: Evidence Frontloading and Pressure-Adaptive Budgeting Relieve RAG Bottlenecks**

A new study addresses efficiency bottlenecks in Retrieval-Augmented Generation (RAG) systems. Unlike existing methods that optimize downstream LLM generation, this approach introduces 'Evidence Frontloading' to load key evidence early and 'Pressure-Adaptive Budgeting' to dynamically allocate resources, effectively relieving the bottleneck between retrieval and generation.
