Action Steps
  1. Build a calibrated dataset to test the temporal validity of retrieved facts
  2. Run experiments to evaluate the performance of cosine similarity in distinguishing contradicted facts
  3. Configure a RAG model to incorporate temporal information and eliminate stale-fact errors
  4. Test the updated model on a benchmark dataset to measure its effectiveness
  5. Apply the temporal validity approach to real-world applications, such as question answering or text generation

Title: Temporal Validity in Retrieval Memory: Eliminating Stale-Fact Errors for AI Agents over Evolving Knowledge

Abstract:
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 The agent then either abstains or serves the superseded fact.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
