A novel classification tree algorithm is proposed to develop models that account for potential discrimination in their predictions. The new splitting criterion incorporates fairness adjustments into the tree-building process, integrating a fairness-aware impurity measure that balances predictive accuracy with fairness across protected groups. The method encourages splits that mitigate discrimination by penalizing unfair splits and utilizing the confidence interval of the fairness metric instead of its point estimate. Experimental results on benchmark and synthetic datasets demonstrate the effectiveness of this approach in reducing discriminatory predictions without sacrificing overall accuracy.
Low GrooveSquid.com (original content) Low Difficulty Summary
A new way to make sure AI doesn’t discriminate is developed. The method uses a special tree-building process that takes into account how fair the predictions are. This helps ensure that the model makes more balanced decisions, even if some groups have different characteristics. By using the uncertainty in fairness metrics, this approach can reduce biased predictions without sacrificing accuracy.
