Decaying Old Memories in Vector Search
25:13
Vector stores like Qdrant and Milvus now ship native decay functions to let newer records beat old ones without database pruning. This look into time-decayed vector search breaks down the core mechanics of linear, exponential, and Gaussian decay curves, how target, scale, and midpoint parameters interact, and why subtle timezone drifts silently ruin ranking. It also examines the architectural…
