Anytime K-Nearest Neighbor Search for Database Applications

Weijia Xu, Daniel P. Miranker, Rui Mao, Smriti Ramakrishnan
2008 First International Workshop on Similarity Search and Applications (sisap 2008)  
Approximate solutions to k-nearest neighbor search provide much needed speed improvement to hard nearest-neighbor problems.  ...  In support of these applications, we explored a search strategy for knearest neighbor searches with MVP-trees that greedily identifies k answers and then improves the answer set monotonically.  ...  The large k value implies a large distance between the query and the kth neighbor.  ...
