Researchers have investigated the impact of temporal aggregation and ranking preservation on decoding-time KV cache compression in large language models. They found that exponential moving average (EMA) aggregation can make scorer modifications indistinguishable at the eviction level, leading to stable retention sets. This led to the development of InertiaKV and InertiaKV-Lazy, methods that improve decode throughput by 1.34-1.46x compared to full refresh methods. The study also explored Score-Free decoding, which maintains average quality while significantly reducing computational cost. AI
