A mutual information library for C and Mex bindings for MATLAB.

This toolbox is aimed at people who wish to use mutual information for feature selection, and provides a range of information theoretic functions. All functions estimate the probabilities from the supplied data vectors. Some example implementations of common mutual information based feature selection algorithms are provided in both C and MATLAB, CMIM - (Fleuret 2004), mRMR - (Peng et al 2005), DISR - (Bontempi & Meyer 2006).

All functions discretise the inputs by rounding down to the nearest integer.

List of functions: Entropy, Conditional Entropy, Joint Entropy Mutual Information, Conditional Mutual Information Renyi's Entropy, Renyi's Mutual Information Creating a joint random variable
