mlpack\+::tree\+::\+Spill\+Tree$<$ Metric\+Type, Statistic\+Type, Mat\+Type, Hyperplane\+Type, Split\+Type $>$} A hybrid spill tree is a variant of binary space trees in which the children of a node can \char`\"{}spill over\char`\"{} each other, and contain shared datapoints. Two new separating planes lplane and rplane are defined, both of which are parallel to the original decision boundary and at a distance tau from it. The region between lplane and rplane is called \char`\"{}overlapping buffer\char`\"{}. For each node, we first split the points considering the overlapping buffer. If either of its children contains more than rho fraction of the total points we undo the overlapping splitting. Instead a conventional partition is used. In this way, we can ensure that each split reduces the number of points of a node by at least a constant factor. This particular tree does not allow growth, so you cannot add or delete nodes from it. If you need to add or delete a node, the better procedure is to rebuild the tree entirely. Three runtime parameters are required in the constructor\+: \begin{DoxyItemize} \item max\+Leaf\+Size\+: Max leaf size to be used. \item tau\+: Overlapping size. \item rho\+: Balance threshold. \end{DoxyItemize} For more information on spill trees, see \begin{DoxyCode} @inproceedings\{ author = \{Ting Liu, Andrew W.
