A Python package to assess and improve fairness of machine learning models.
AIF360
AIF360 provides fairness metrics and explanations for datasets and models, along with algorithms to mitigate bias.

About AIF360
AIF360 is an open-source library, available in Python and R, for detecting and mitigating bias in machine learning models and datasets. It is intended for use across the AI application lifecycle. The package includes metrics for testing datasets and models for bias, explanations for those metrics, and algorithms for reducing bias in datasets and models. The project states that it is designed to move algorithmic fairness research into practice in areas such as finance, human capital management, healthcare, and education.
The Python package is installed with pip from PyPI or within a conda environment. The project lists supported Python versions 3.10 to 3.13 on macOS, Ubuntu, and Windows. It requires specific versions of many Python packages, which may conflict with other projects, so the project recommends a virtual environment. The source states that the library is still in development. It also notes that the number of available metrics and algorithms can make it hard to choose the right one for a given use case, and it links to guidance material for that choice.
