I'm sorry that I cannot help you...
But I wonder is this K-D Tree just the data structure that is used in Machine Learning? I remember that there is a classification algorithm which is referred to as K-nearest neighbors, and K-D Tree is used for data preprocessing.
Yes, K-D tree is the data structure used for KNN method in ML. Also K-D tree is helpful in databases for performing queries with multidimensional search key.
