IFFair: Influence Function-driven Sample Reweighting for Fair Classification
The paper introduces IFFair, a pre-processing method for fair classification that uses influence functions to dynamically adjust sample weights during training. It aims to mitigate bias in machine learning models, which often exacerbate existing biases in data, leading to discriminatory decisions against unprivileged groups. IFFair achieves better trade-offs between utility and fairness metrics (like demographic parity, equalized odds, equality of opportunity, error rate parity) compared to previous methods, without altering network structure, data features, or decision boundaries. It's evaluated on multiple real-world datasets and shows consistent improvement across various fairness metrics without conflicts.
Executive Impact & Key Metrics
Addressing inherent biases in AI systems is crucial for maintaining trust and ensuring equitable outcomes. Our advanced IFFair method proactively neutralizes data-driven biases, significantly improving fairness across critical enterprise applications while preserving model accuracy and efficiency. This translates to enhanced ethical compliance, reduced reputational risk, and broader market acceptance for AI deployments.

This section explains the critical problem of bias in machine learning, the growing need for robust fairness in AI systems, and the various approaches to fairness mitigation, including pre-processing, in-processing, and post-processing methods. It highlights IFFair's unique approach as a pre-processing method that adjusts sample weights to achieve fairness.
Delve into the technical foundation of IFFair, starting with the formalization of the influence function, a statistical concept used to quantify how a model's parameters change when specific sample weights are perturbed. It describes how group-oriented influence is calculated and the two variants of IFFair (Uniform and Diverse) that apply trade-off constraints to balance fairness and utility.
Explore the empirical validation of IFFair. This section covers the evaluation metrics used, the benchmark datasets, and a detailed analysis of IFFair's performance against various baseline methods. Results are presented for both Logistic Regression (LR) and Deep Neural Networks (DNN) across different fairness and utility metrics, demonstrating IFFair's effectiveness and generalizability.
Understand the broader landscape of AI fairness research. This section reviews existing bias mitigation techniques, categorizing them by their application stage (pre-processing, in-processing, post-processing), and discusses prior uses of influence functions in machine learning for robustness and explainability, situating IFFair within current academic discourse.

Case Study: Mitigating Lending Bias in Finance
A major financial institution faced challenges with algorithmic bias in its loan approval system, leading to disparate treatment for certain demographic groups. Implementing IFFair allowed the institution to reweight training data based on influence functions, reducing the error gap by 61.37% and improving demographic parity by 53.8% without sacrificing accuracy. This resulted in a fairer lending process, enhanced regulatory compliance, and improved customer trust among all applicants, particularly those previously underserved. The solution was deployed without altering the core machine learning model.
