The European Commission and the Federal Trade Commission have both made major pronouncements about artificial intelligence (AI) enforcement, highlighting the need to prevent troubling outcomes from algorithm use. The auditing of AI algorithms is a developing practice addressing this need, with Twitter earlier this year buying one of the few specialist firms. This third article in a series examines two recently completed audits of widely used AI services and presents insights from algorithm auditors and AI incident responders about the practical role of AI audits. The first article covered compliance essentials for AI/machine learning tools, and the second article supplied questions to guide AI oversight.
