On the opportunities and risks of Algorithmic Decision Systems

on the March 29, 2019

Claude Castelluccia and Daniel Le Métayer, Inria research directors and members of the Grenoble Alpes Data Institute, have written a report for the European Parliament on the opportunities and risks related to the use of Algorithmic Decision Systems.

Algorithm Decision Systems often rely on the analysis of large amounts of personal data to infer correlations or, more generally, to derive information deemed useful to make decisions. Human intervention in the decision-making may vary, and may even be completely out of the loop in entirely automated systems. In many situations, the impact of the decision on people can be significant, such as on access to credit, employment, medical treatment, judicial sentences, among other things. Entrusting ADS to make or to influence such decisions raises a variety of different ethical, political, legal, or technical issues, where great care must be taken to analyse and address them correctly. If they are neglected, the expected benefits of these systems may be negated by the variety of risks for individuals (discrimination, unfair practices, loss of autonomy, etc.), the economy (unfair practices, limited access to markets, etc.), and society as a whole (manipulation, threat to democracy, etc.). This study reviews the opportunities and risks related to the use of ADS. It presents existing options to reduce these risks and explain their limitations. It also sketches some options to benefit from the tremendous possibilities of ADS while limiting the risks related to their use. Beyond providing an up-to-date and systematic review of the situation, the study gives a precise definition of a number of key terms and an analysis of their differences to help clarify the debate. The main focus of the study is the technical aspects of ADS. However, to broaden the discussion, other legal, ethical and social dimensions are considered.

The report, entitled "Understanding algorithmic decision-making: Opportunities and challenges", is available on European Parliament website.
