How to use:

RPTree.py

this python file contains the BinaryTree class, which performs the following tasks:

  • construct_tree
  • get_leaf_nodes
  • preorder_search

RunMain.py

this python file contains the driver code to create BinaryTree instance, then performs the following tasks:

  • picks a random test sample, and removes it from the dataset.
  • creates the rpTree from the dataset.
  • performs k-nn search on the rpTree to find the nearest neighbors for the test sample.
