Implementation of Feature Relevance Bounds method to perform Feature Selection and further analysis.

Project description

Feature Relevance Intervals - FRI

Feature Relevance Intervals - FRI

Travis (.org) Coveralls github DOI Open In Colab PyPI PyPI - Python Version GitHub

FRI is a Python 3 package for analytical feature selection purposes. It allows superior feature selection in the sense that all important features are conserved. At the moment we support multiple linear models for solving Classification, Regression and Ordinal Regression Problems. We also support LUPI paradigm where at learning time, privileged information is available.


Check out our online documentation at There you can find a quick start guide and more background information.

You can also run the guide directly without setup online here.


FRI requires Python 3.6+.

For a stable version from PyPI use

$ pip install fri


Please refer to the documentation for advice. For a quick start we provide a simple guide which leads through the main functions.
