Abstract Machine learning techniques have been used in the construction of automatic systems in order to deal with several practical problems. Examples include the applications in credit systems, which evaluate if an individual will lead to a possible default with respect to the received credit, or in judicial systems, which predict whether the defendant under trial may re-offend. In general, the purpose of such systems is to aid decision makers in their complex tasks, which can be difficult to be dealt with due to the large amount of available information or the users inherent biases. However, what is frequently observed in real situations is that some algorithms promotes discrimination against specific groups of individuals. Therefore, there is a need in the development of machine learning techniques that take into account characteristics such as fairness and transparency in the construction of the adopted system. The goals of this research project lies on this context. More precisely, the aforementioned concerns will be addressed both in the pre-processing step, by means of an approach based on principal component analysis, and in both training and classification steps, through the use of multi-objective optimization and Choquet integrals. It is worth mentioning that, by using the proposed methods, it will be possible to build automatic systems whose application does not promote ethical disparities with respect to the individuals under analysis. Moreover, our proposals are generalist, i.e., they can be used to deal with several problems in machine learning. | |
