Consequently, explaining these decisions and identifying responsibilities has become a challenge. As a result, a new field of research on algorithmic fairness has emerged. In this area, detecting biases and mitigating them is essential to ensure fair and discrimination-free decisions. This paper contributes with: (1) a categorization of biases and how these are associated with different phases of an AI model’s development (including the data-generation phase); (2) a revision of fairness metrics to audit the data and AI models trained with them (considering agnostic models when focusing on fairness); and, (3) a novel taxonomy of the procedures to mitigate biases in the different phases of an AI model’s development (pre-processing, training, and post-processing) with the addition of transversal actions that help to produce fairer models.}, year = {9998}, journal = {International Journal of Interactive Multimedia and Artificial Intelligence}, volume = {In press}, chapter = {1}, number = {In press}, pages = {1-13}, month = {11/2023}, issn = {1989-1660}, url = {https://www.ijimai.org/journal/sites/default/files/2023-11/ip2023_11_001.pdf}, doi = {10.9781/ijimai.2023.11.001}, }
