🤖 AI Summary
Bias mitigation methods in machine learning fairness research suffer from poor portability and comparability due to their strong dependence on specific domains, tasks, and models. Method: This paper introduces BiMi Sheets—the first structured documentation paradigm tailored for bias mitigation methods—comprising standardized information sheets that systematically encode meta-information across key design dimensions, including fairness definitions, intervention stages, and applicability conditions. The information architecture is grounded in domain-informed knowledge modeling and implemented via an open-source web platform (bimisheet.com). Contribution/Results: The project establishes the first structured database of bias mitigation methods, significantly enhancing their interpretability, comparability, and reusability. By formalizing method specifications, BiMi Sheets effectively alleviates the “portability trap,” reducing both cognitive and engineering overhead for practitioners evaluating and selecting appropriate mitigation techniques.
📝 Abstract
Over the past 15 years, hundreds of bias mitigation methods have been proposed in the pursuit of fairness in machine learning (ML). However, algorithmic biases are domain-, task-, and model-specific, leading to a `portability trap': bias mitigation solutions in one context may not be appropriate in another. Thus, a myriad of design choices have to be made when creating a bias mitigation method, such as the formalization of fairness it pursues, and where and how it intervenes in the ML pipeline. This creates challenges in benchmarking and comparing the relative merits of different bias mitigation methods, and limits their uptake by practitioners. We propose BiMi Sheets as a portable, uniform guide to document the design choices of any bias mitigation method. This enables researchers and practitioners to quickly learn its main characteristics and to compare with their desiderata. Furthermore, the sheets' structure allow for the creation of a structured database of bias mitigation methods. In order to foster the sheets' adoption, we provide a platform for finding and creating BiMi Sheets at bimisheet.com.
