Prune, Don't Rebuild: Efficiently Tuning I^±-Reachable Graphs for Nearest Neighbor Search

Tian Zhang, Ashwin Padaki, Jiaming Liang +2

Vector similarity search is an essential primitive in modern AI and ML applications. Most vector databases adopt graph-based approximate nearest neighbor (ANN) search algorithms, s…

Data-Agnostic Cardinality Learning from Imperfect Workloads

Peizhi Wu, Rong Kang, Tieying Zhang +3

Cardinality estimation (CardEst) is a critical aspect of query optimization. Traditionally, it leverages statistics built directly over the data. However, organizational policies (…

Low Rank Learning for Offline Query Optimization

Zixuan Yi, Yao Tian, Zachary G. Ives +1

Recent deployments of learned query optimizers use expensive neural networks and ad-hoc search policies. To address these issues, we introduce \textsc{LimeQO}, a framework for offl…
