![]() As a general rule, if the dimensionality is k, the number of points in the data, N, should be N ≫ 2 k. K-d trees are not suitable, however, for efficiently finding the nearest neighbor in high dimensional spaces. K-d trees are a special case of binary space partitioning trees. range searches and nearest neighbor searches). k-d trees are a useful data structure for several applications, such as searches involving a multidimensional search key (e.g. ![]() (See links for details on variance)Ī k-d tree (short for k-dimensional tree) is a space-partitioning data structure for organizing points in a k-dimensional space.
