Temporal Validity in Retrieval Memory: Eliminating Stale-Fact Errors for AI Agents over Evolving Knowledge
arXiv:2606.26511v1 Announce Type: cross Abstract: Retrieval-augmented generation (RAG) gives agents access to accumulated knowledge, but has no model of time. When a fact changes (e.g., a function is renamed or API restructured), RAG retrieves both the stale and current value with near-identical embedding similarity. The agent then either abstains or serves the superseded fact. We show this is a structural problem: on a calibrated dataset, cosine similarity distinguishes a contradicted fact from a duplicated one with AUROC 0.59 (near chance), as contradictions are often more embedding-similar
The rapid deployment and increasing sophistication of AI agents highlight the immediate need to address their reliability and accuracy, especially as they integrate into dynamic knowledge environments.
Improving the temporal validity of AI agents is crucial for their trustworthiness and effective autonomous operation, preventing critical errors from stale or contradicted information.
AI agents will become significantly more reliable in environments where underlying data is constantly evolving, reducing incidents of incorrect or outdated responses.
