An eigenvalue-based pivot selection strategy for efficient indexing and searching in metric spaces

Pivots are used widely during indexing and searching in metric spaces. We maintain the distances from pivots to data objects to be indexed so the pre-computed distances can be used to prune unpromising objects during the search process. The search efficiency depends on the pivots used, but choosing...
