Sliceline

Sliceline is a Python library for fast slice finding for Machine Learning model debugging.

It is an implementation of SliceLine: Fast, Linear-Algebra-based Slice Finding for ML Model Debugging, from Svetlana Sagadeeva and Matthias Boehm of Graz University of Technology.

👉 Getting started

Given an input dataset X and a model error vector errors, SliceLine finds the top slices in X that identify where a ML model performs significantly worse.

You can use sliceline as follows:

from sliceline.slicefinder import Slicefinder

slice_finder = Slicefinder()

slice_finder.fit(X, errors)

print(slice_finder.top_slices_)

X_trans = slice_finder.transform(X)

We invite you to check the demo notebooks for a more thorough tutorial:

🛠 Installation

Sliceline is intended to work with Python 3.9 or above. Installation can be done with pip:

pip install sliceline

There are wheels available for Linux, MacOS, and Windows, which means that you most probably won’t have to build Sliceline from source.

You can install the latest development version from GitHub as so:

pip install git+https://github.com/datadome/sliceline --upgrade

Or, through SSH:

pip install git+ssh://git@github.com/datadome/sliceline.git --upgrade
