The proposed conceptual model for real-time tracking and correction of individual discrimination in machine learning systems offers several key characteristics and advantages compared to previous methods .
-
Real-time Monitoring and Correction: Unlike traditional offline fairness testing methods, the proposed model focuses on online fairness testing, evaluating the fairness of an ML system during its operation in real-time . This continuous monitoring allows for the immediate detection of discriminatory outcomes, enabling timely intervention to ensure fair and unbiased decisions .
-
Human-in-the-Loop Approach: The model incorporates a human review component, empowering human reviewers to intervene and correct any detected discrimination . This human oversight ensures that decisions made by the ML system are fair and ethical, preventing disadvantaged groups from being unfairly impacted by discriminatory outcomes .
-
Utilization of Counterfactual Explanations: The framework leverages counterfactual explanations to identify instances of discrimination in ML systems . By generating counterfactual examples of input instances, the model provides alternative scenarios that help human reviewers understand how the ML model makes judgments, enhancing transparency and accountability .
