Model fairness audits
Model fairness audits are systematic evaluations of machine learning models to assess whether their predictions are equitable across different groups, such as those defined by race, gender, or age. These audits involve analyzing model outcomes for potential biases or disparities, identifying sources of unfairness, and recommending corrective actions. The goal is to ensure that automated decisions do not perpetuate or amplify existing inequalities, thereby promoting ethical and responsible use of artificial intelligence systems.

- Understand a practical fairness audit workflow: data review, metric selection, bias testing, and remediation.
❓ Frequently Asked Questions
What is a model fairness audit?
A systematic evaluation of an AI model to assess whether its predictions are equitable across protected groups (e.g., race, gender, age) and to identify potential biases or disparities.
What groups are typically considered in fairness audits?
Protected attributes such as race, gender, age, ethnicity, disability, and sometimes socio-economic status; audits may also examine intersections (e.g., race × gender).
What metrics are used to assess fairness?
Group-wise performance metrics (accuracy, precision, recall, calibration) across groups, and fairness-specific metrics like disparate impact, equal opportunity difference, demographic parity, and equalized odds.
What steps are involved in conducting a fairness audit?
Define protected groups and outcomes, analyze data and model results by group, identify sources of bias (data, labels, features, model design), and document findings and limitations.
What can be done to address fairness issues found in an audit?
Apply mitigation strategies such as data reweighting or re-sampling, feature adjustments, model or threshold changes, and ongoing governance and monitoring.
