Alondra Nelson, former acting director of the White House Office of Science and Technology Policy under President Joe Biden and key architect of the Blueprint for an AI Bill of Rights, is the co-author of a new book, "Audi," which examines the process of testing models to assess risk of bias and potential harms. Nelson argues that auditing AI systems is a powerful tool for accountability and can be applied to individuals with technical expertise. The book focuses on AI that is biased against protected identity groups. Nelson also discusses the potential for political bias in AI, which could violate civil liberties at the same time as civil rights law and the European Union.
