Recall-Aware Early Termination in Approximate Nearest Neighbor Search

This paper proposes an adaptive framework for ANNS that explicitly incorporates user-specified recall requirements into the search process by employing an early termination strategy, and introduces two learning-based mechanisms, one for dynamically predicting the achieved recall during the search and triggers early ter...

Recall-Aware Early Termination in Approximate Nearest Neighbor Search

Approximate nearest neighbor search (ANNS) is a fundamental operation in large-scale vector retrieval systems, where achieving high recall under strict latency constraints is essential. Existing ANNS approaches typically control recall using fixed search parameters, such as a predefined candidate neighbor set (CNS) siz...
