Feature Relevance Intervals - FRI
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.
Please refer to the documentation for advice. For a quick start we provide a simple guide which leads through the main functions.
FRI requires Python 3.6+.
For a stable version from
$ pip install fri
or with new versions of
pip (>=19?) you can clone the repository and run
$ pip install .
in the folder on the
Check out our online documentation here. There you can find a quick start guide and more background information.
You can also run the guide directly online without setup here.
For dependency management we use the newly released poetry tool.
If you have
poetry installed, use
$ poetry install
inside the project folder to create a new
venv and to install all dependencies.
To enter the newly created
$ poetry env
to open a new shell inside.
Or alternatively run commands inside the
poetry run ....
$ poetry run portray in_browser
to compile the files into html and launch a browser to preview changes.
