Fairness-aware machine learning and data mining

Nowadays, many decisions are made using predictive models built on historical data, for example, automated CV screening of job applicants, credit scoring for loans, or profiling of potential suspects by the police. Algorithms decide upon the prices we pay, the people we meet, or the medicine we take. 

Growing evidence in the media and research suggests that decision making by algorithms can potentially discriminate people. This may happen even if the computing process is fair and well-intentioned. This is because most data mining methods are based upon assumptions that the historical data is correct, and represents the population well, which is often not true in reality. Moreover, usually predictive models are optimized for performing well in the majority of the cases, not taking into account who is affected the worst by the remaining inaccuracies.

Fairness-aware machine learning and data mining studies in which circumstances algorithms may become discriminatory, and how to make predictive models free from discrimination, when data, on which they are built, may be biased, incomplete, or even contain past discriminatory decisions.
