Not All Memories Age the Same: Autodiscovery of Adaptive Decay in Knowledge Graphs

ArXi:2604.26970v1 Announce Type: cross Knowledge graphs used for retrieval treat all facts as equally current. Existing temporal approaches apply uniform decay, using a single forgetting curve regardless of knowledge type. We show this is fundamentally misspecified: different knowledge types exhibit different temporal dynamics, and the core retrieval problem is not latency or throughput but identifying what is important at query time.
