“…To address this issue, numerous debiasing frameworks have been proposed for identifying and mitigating the potential risks posed by dataset or algorithmic biases. These frameworks can be categorized into pre-processing (Li and Vasconcelos 2019;Sagawa et al 2020b;Kamiran and Calders 2012), in-processing (Sagawa et al 2020a;Sohoni et al 2020;Wang et al 2019;Zhang, Lemoine, and Mitchell 2018;Gong, Liu, and Jain 2020;Seo, Lee, and Han 2021;Ragonesi et al 2021;Wang et al 2020;Guo et al 2020), and post-processing (Hardt, Price, and Srebro 2016;Zhao et al 2017) (Chu, Kim, and Han 2021;Gong, Liu, and Jain 2020;Ragonesi et al 2021), or robust optimization (Sagawa et al 2020a;Sohoni et al 2020;Seo, Lee, and Han 2021). Postprocessing methods modify the predicted outputs to meet fairness criterion, mainly by calibrating the outputs (Hardt, Price, and Srebro 2016;Zhao et al 2017).…”
