Minimum Description Length Binning

This is an implementation of Usama Fayyad's entropy based expert binning method.

Please read the original paper here for more information.

Installation and Usage

You'll need to install Cython and numpy first, if you haven't already.

This project is not yet on PyPI, but you can install the lastest master through pip like so:

$ pip install https://github.com/hlin117/mdlp-discretization/archive/master.zip

Here's a quick usage example:

>>> from discretization import MDLP
>>> from sklearn.datasets import load_iris
>>> iris = load_iris()
>>> X = iris.data
>>> y = iris.target
>>> mdlp = MDLP()
>>> X_discrete = mdlp.fit_transform(X, y)

Afterwards, X_discrete will have the same shape as X but will be integer valued.

Tests

To run the unit tests, make sure you have nose installed. Afterwards,

$ make test

should do the trick.
