AI Fairness 360: Understand and mitigate bias in ML models

AI Fairness 360, an LF AI incubation project, is an extensible open source toolkit that can help users examine, report, and mitigate discrimination and bias in machine learning models throughout the AI application lifecycle. It is designed to translate algorithmic research from the lab into the actual practice of domains as wide-ranging as finance, human capital management, healthcare, and education. The toolkit is available in both Python and R. IBM moved AI Fairness 360 to LF AI in July 2020.


10 state-of-the-art bias mitigation algorithms

Developed by the research community and include algorithms such as optimized preprocessing, reweighing, adversarial de-biasing, reject option classification, disparate impact remover, learning fair representations, equalized odds post-processing, meta-fair classifier, and more.

70 Fairness Metrics

Over seventy metrics that can help quantify aspects of individual and group fairness including statistical parity difference, equal opportunity difference, average odds difference, disparate impact, Theil index, Euclidean distance, Manhattan distance, Mahalanobis distance and more.

Industrial Applications

Packed with tutorials demonstrating an industrial use case using the toolkit that offer a deeper, data scientist-oriented introduction. Examples: Credit Scoring and Medical Expenditures.
