MRmD is a supervised discretization framework that can balance discrimination power and generalization ability.

This is a source code of MRmD for a naive Bayes classifier using MATLAB. The version of MATLAB should be >=2019b.

• To successfully run the code, you need to install the Bioinformatics Toolbox and Statistics and Machine Learning Toolbox.

• Download the source file, place it in MATLAB and then run the main.m file.

We provide a sample dataset flare.data2 for one of the used datasets flare-solar in the paper. The detailed descriptions of all datasets used in the paper can be found at https://archive.ics.uci.edu/ml/index.php.
