Entity-Collision: A Stratified Protocol for Attributing Retrieval Lift in Agent Memory
Researchers propose entity-collision, a standardized testing protocol for evaluating retrieval systems in agent memory applications. The protocol isolates embedder performance from lexical overlap by construction, revealing that encoder capacity alone doesn't guarantee better retrieval—MiniLM-384 outperforms larger models on mixed query types despite having fewer parameters than BGE-large.
