Pruning removes potentially unnecessary subtrees from the decision tree. This MATLAB implementation allows for pruning using 2 different algorithms: (1) Error-based pruning from C4.5: Programs for Machine Learning, and (2) Minimum misclassified points algorithm. A d-dimensional aabb-tree implementation in MATLAB / OCTAVE.In contrast to other geometric tree types (quadtrees, kd-trees, etc), aabb- trees are applicable to collections of general objects, rather than just points. This is a very fast implementation of the original kmeans clustering algorithm without any fancy acceleration technique, such as kd-tree indexing and triangular inequation. (actually the fastest matlab implementation as far as I can tell.) implementation of these methods in Matlab environments. 1 Introduction.approach to develop RRT efficiency is sampling strategy which depends on kd-tree, voronoi [11] or. filling-space algorithms [12].

Your data does have a tree structure, however you are not utilising this in your implementation. Instead the implemented code is a computational hungry version of a look up table (actually 2 tables), that stores the data and the relational data for the tree. A concise introduction to matlab.
