scikit-protopy

Prototype Selection and Generation Toolbox based on scikit-learn.

This project was started in 2014 by Dayvid Victor as a result of his masters and on-going PhD at Federal University of Pernambuco.

The aim of this project is to provide Prototype Selection (PS) and Prototype Generation (PG) techniques to be applied where instance reduction is needed (noisy sensitive domains, imbalanced datasets, high density clusters ...).

Right now, this project is referenced in the scikit-learn official wiki (https://github.com/scikit-learn/scikit-learn/wiki/Third-party-projects-and-code-snippets). Hopefully, the PS/PG techniques might be included in the scikit-learn project anytime soon.

Dependencies

This is designed to work with:

  • Python 2.6+
  • scikit-learn == 0.16.0
  • Numpy >= 1.3
  • SciPy >= 0.7
  • Matplotlib >= 0.99.1. (for examples, only)

Install

To install, use::

sudo python setup.py install

To install via easy_install, use::

sudo easy_install .
