Introduction

This video explains how to build approaches to identify and mitigate bias and inequities within analytical models. It emphasizes the importance of fairness, accuracy, and trustworthiness in model outputs and provides methods for evaluating and correcting biases.

Key Takeaways

• Identifying and Mitigating Bias: The video stresses the importance of identifying and reducing bias in analytical models to ensure fairness, accuracy, and user trust.
• Bias Sources and Types: Common biases like sampling bias, measurement bias, and algorithmic bias are discussed, highlighting their origins in imbalanced data, flawed assumptions, and systemic inequalities.
• Evaluation Methods: The video suggests using fairness metrics (e.g., demographic parity, equal opportunity, disparate impact) to evaluate model bias across different demographic groups. Generative AI tools can assist in generating evaluation reports.
• Bias Mitigation Strategies: Several strategies for mitigating bias are presented, including resampling data, adjusting weights, modifying algorithms, and employing pre-processing, in-processing, and post-processing methods. Generative AI can suggest appropriate correction techniques.
• Validation and Continuous Monitoring: The importance of validating fairness improvements after mitigation and continuously monitoring models post-deployment is highlighted. Comparing before-and-after results ensures that bias reduction doesn't compromise accuracy.
