Webk-Dimensional Trees. The general idea of KD-trees is to partition the feature space. We want discard lots of data points immediately because their partition is further away than our k closest neighbors. We partition the following way: Divide your data into two halves, e.g. left and right, along one feature. WebKDTree for fast generalized N-point problems Read more in the User Guide.
