# 激进KV压缩解码：时间聚合与排序保留起关键作用

针对解码时KV缓存压缩的研究发现，在激进压缩下，设计更优的token评分函数不如时间聚合规则关键。论文强调，评分跨解码步骤的聚合方式及原有排序保留对性能影响更大，为未来KV驱逐策略提供了新方向。

## English Version

**KV Cache Eviction Study: Temporal Aggregation and Ranking Matter**

New research on decoding-time KV cache compression shows temporal rules for aggregating scores matter more than better scoring functions under aggressive eviction. Preserving ranking and aggregation across decode steps significantly impacts performance, guiding future eviction strategy design.
