memory-staleness

This paper empirically studies how VLM agents with persistent spatial memory fail when memory becomes stale, using a dynamic FrozenLake testbed. It finds that trusting stale memory can more than double death rates, and that read-time auditing helps but does not fully close the gap.

本文实证研究了视觉语言模型智能体中的空间记忆过时性问题，发现模型常常忽略矛盾的视觉证据，并且信任过时记忆会增加安全风险。作者提出了审计机制，但表明在记忆-观察冲突下的视觉接地仍是一个重大开放挑战。
