S-CLASSY

Discovering Rule Lists with Preferred Variables (S-CLASSY)

This repository contains the code for using preferred variables to discover Hybrid Rule Lists (HRL) for univariate or multivariate classification in Data Mining. These models use the Minimum Description Length (MDL) principle as selection criterion.

Dependencies

This project was written for Python>=3.7. All required packages from PyPI are specified in the requirements.txt. NOTE: This list of packages includes the gmpy2 package. You can install the dependencies locally:

pip install -r requirements.txt

Execution guide

  • Open: run_S-CLASSY.ipynb or run_S-CLASSY_cross_validation.ipynb in the Jupyter Notebook dashboard by clicking on the name of the file in the dashboard.
  • Update the configurations regarding the datasets tha you want to load (for more info read the comments in the .ipynb file).
  • Run the file.
