Approximate Nearest Neighbor Search
An algorithm for efficiently finding the nearest points in high-dimensional vector spaces. It is commonly used in vector databases and semantic retrieval systems to balance speed and accuracy.
Timeline (last 90 days)
Vector embedding retrieval relies on approximate nearest neighbor search, and results are affected by embedding model version, index parameters, and floating-point errors, potentially producing differences between runs.
