Episode 16 — Mitigating Bias

Measuring bias is only the first step; mitigation strategies are required to reduce unfair outcomes in AI systems. This episode introduces three broad categories of bias mitigation: pre-processing, in-processing, and post-processing. Pre-processing techniques focus on balancing datasets through re-sampling, re-weighting, or augmentation. In-processing integrates fairness constraints directly into algorithms, including adversarial debiasing and regularization methods. Post-processing adjusts model outputs, such as calibrating thresholds or re-ranking results, to correct disparities. Learners gain an understanding of how each stage of the AI lifecycle offers opportunities for reducing bias.The discussion expands with sector examples. In hiring, re-sampling ensures better representation of underrepresented groups. In healthcare, in-processing methods help reduce diagnostic disparities across populations, while in finance, post-processing adjustments balance approval rates without discarding predictive accuracy. Challenges are acknowledged, including trade-offs between fairness and accuracy, the computational costs of mitigation, and the reality that no single method can fully eliminate bias. Learners are shown how combining techniques with governance oversight and human judgment creates more robust outcomes.
