safetycage 0.0.61

SafetyCage is a Python package for detecting misclassified predictions from machine learning models in classification tasks. It provides a unified interface for multiple statistical detection methods, enabling users to quantify prediction reliability and flag potentially incorrect outputs across different models and datasets easily.

It is available on PyPI here: https://pypi.org/project/safetycage/.

Background

The idea behind safetycage is that we can find statistics on each predicted sample and compare that statistic to some statistic threshold to predict whether the sample prediction was incorrectly classified.

Description

Machine learning models can produce incorrect predictions with high confidence. SafetyCage addresses this by providing post-hoc misclassification detection methods that operate on model outputs or internal representations.

The package includes several methods:

• MSP (Maximum Softmax Probability)
• DOCTOR (Error probability estimation)
• Mahalanobis (Distance-based statistical testing)
• SPARDACUS (Projection + density estimation approach)

Each method outputs a statistic or p-value that reflects how likely a prediction is to be incorrect.

Alternatively, you can implement your own method by initializing a base class from the safetycage abstract base class, which defines how methods should be implemented.

Requirements

Currently, safetyCage requires Python 3.11.7. Consider creating an environment for your project with safetycage that uses Python 3.11.7.

We are working to make this more flexible.

Installation

Install via pip using the command:

pip install safetycage

The dependencies should be automatically installed when you install safetycage. If not, consider seeing the dependencies listed in the pyproject.toml available on GitHub.

Tutorials & Examples

To learn how to use safetycage, check out the safetycage tutorials available at https://github.com/safety-cage/safetycage-tutorials. These provide full examples and tutorials on how to use safetycage, and thus also providing scripts to train models to test the safetycage methods on!

Acknowledgment

The MSP method was introduced by Hendrycks and Gimpel in A Baseline for Detecting Misclassified and Out-of-Distribution Examples in Neural Networks.

The DOCTOR method was introduced by Granese et al. in DOCTOR: A Simple Method for Detecting Misclassification Errors.

A proper citation for these methods is provided in the docstring of the code using these methods.

A special thank you goes to previous co-authors of the methods we have built, Filippo Remonato, Shawn Benedict, and Albert Ndur-Osei.
