A novel approach to fairness in linear regression from a Bayesian perspective.
R. Jiménez Llamas, E. CARRIZOSA, P. Ramirez Cobo
Fairness in statistical and machine learning aims to avoid discriminatory solutions inherited from biases in datasets regarding to sensitive variables. In this work we undertake the fairness issue in a linear regression setting by means of Bayesian tools. In particular, under the Normal-Gamma model our method forces fair solutions by selecting the hyper-parameters in a way analogous to Empirical Bayes. The considered fairness measure, the average difference between sensitive and non-sensitive populations, avoids the need for individual information regarding the sensitive classes, which may be unavailable for privacy issues. As numerical illustrations show, the method provides a solution that balances between the fairness degree and an adequate fit to the data.
Keywords: Fairness, Bayesian linear models, Normal-Gamma probability distribution, Empirical Bayes, Gram–Schmidt process.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
