The AI Act defines an AI system as “a machine-based system designed to operate with varying levels of autonomy and that may exhibit adaptiveness after deployment and that, for explicit or implicit objectives, infers, from the input it receives, how to generate outputs such as predictions, content, recommendations, or decisions that can influence physical or virtual environments”.
In simple terms, it broadly defines an AI system as any system that, with a degree of autonomy, infers inputs to determine how to produce outputs (such as predictions, recommendations, decisions, or content) that can impact physical or virtual environments.
