Module 6: Model Evaluation and Bias Mitigation

Measure performance disparities across subpopulations, such as skin tone in facial recognition or geographic regions in satellite imagery.
Conduct confusion matrix analysis to identify systematic misclassifications requiring label refinement or data rebalancing.
Use Grad-CAM or SHAP visualizations to audit model attention and detect reliance on spurious features.
