To further reduce the computing time of the algorithm, nearest neighbour search technique is applied to the algorithm. Experiments on numerical and image database show the algorithm cannot only improve the classification accuracy, but also reduce runtime....
This paper studies k-nearest-neighbor (kNN) search on R-tree-based structures storing historical information about trajectories. We develop BFPkNN, an efficient best-first based algorithm for handling kNN search with arbitrary values of k, which is I/O o
(NearestNeighborSearch):最近邻查询是最重要的空间查询之一,也是文本着 重考虑的类型。其定义是:给定一个查询点q和一个距离度量(有欧几里德距离、 曼哈顿距离等),一个最近邻查询找出一个离查询点q最近的空间数据对象。它 的一般化形式为k(k=1)最近邻查询,定义为:给定一个查询点q,一个正整数k ...
