AI system

Definition

A machine-based system that operates with some autonomy, may adapt after it is deployed, and infers from the input it receives how to generate outputs such as predictions, content, recommendations or decisions that can influence physical or virtual environments. This is the EU AI Act's definition, which follows the OECD's; whether software is an "AI system" decides whether the Act applies to it at all.
