k-dtree实现近邻查找，首先构造根节点，根节点对应于整个k维空间，包含所有的实例点，（至于如何选取划分点，有不同的策略。最常用的是一种方法是：对于所有的样本点，统计它们在每个维上的方差，挑选出方差中的最大值，对应的维就是要进行数据切分的维度。
K-dtree for nearest neighbor search.Firstly, the root node is constructed, which corresponds to the whole k-dimensional space and contains all the instance points. The most commonly used method is: for all sample points, the variance of each dimension is counted, and the maximum value of variance is selected. The corresponding dimension is the dimension for data segmentation. (2020-07-17, C/C++, 12127KB, 下载0次)
