What fairness metric should I use when optimizing equalized odds?

Asked on Oct 09, 2025

Answer

When optimizing for equalized odds, you should focus on fairness metrics that evaluate the balance of true positive rates and false positive rates across different groups. Equalized odds specifically requires that these rates are equal for all demographic groups. This ensures that the model's performance is consistent, regardless of group membership.

Example Concept: Equalized odds is a fairness criterion that demands equal true positive rates and false positive rates across all demographic groups. To measure this, you can calculate the difference in these rates between groups and aim to minimize these disparities. This approach helps ensure that the model does not systematically favor or disadvantage any particular group.

Additional Comment:

Consider using fairness dashboards to visualize and compare these rates across groups.
Regularly audit your model's performance to ensure compliance with equalized odds.
Be aware of the trade-offs between fairness and other performance metrics like accuracy.
Use fairness-aware algorithms or post-processing techniques to adjust predictions if disparities are detected.
