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

Tests

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

$ make test

should do the trick.

Installation and Usage

This code was built using Cython, so you have to run the makefile in the directory.

$ pip3 install mdlp

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

I recommend creating a virtual environment for this project.
