The Merkurion approach for similarity searching optimization in Database Management Systems

作者:

Highlights:

• A similarity-based extension for DBMS's query optimizers is proposed.

• Both logical and physical optimization of similarity queries are addressed.

• Some similarity-based synopses are more suitable than others for logical/physical optimizations.

• Boosted k-nearest neighbors algorithms may outperform the incremental approach.
