Bias Mitigation for Machine Learning Classifiers: A Comprehensive Survey
It addresses the problem of bias in ML for practitioners by providing a comprehensive overview, but it is incremental as a survey without new experimental results.
This paper surveys bias mitigation methods for fairness in machine learning classifiers, reviewing 341 publications to categorize approaches and evaluation practices, aiming to guide practitioners in developing and assessing new methods.
This paper provides a comprehensive survey of bias mitigation methods for achieving fairness in Machine Learning (ML) models. We collect a total of 341 publications concerning bias mitigation for ML classifiers. These methods can be distinguished based on their intervention procedure (i.e., pre-processing, in-processing, post-processing) and the technique they apply. We investigate how existing bias mitigation methods are evaluated in the literature. In particular, we consider datasets, metrics and benchmarking. Based on the gathered insights (e.g., What is the most popular fairness metric? How many datasets are used for evaluating bias mitigation methods?), we hope to support practitioners in making informed choices when developing and evaluating new bias mitigation methods.
