Luo Yanmin, Kazutaka Furuse, Hanxiong Chen, Nobuo Ohbo · 2007
Aggregate Nearest Neighbor Queries are much more complex than Nearest Neighbor queries, and pruning strategies are always utilized in ANN queries. Most of the pruning methods are based on the data index mechanisms, such as R-tree. But for the well-known curse of dimensionality, ANN search could be m
