Which of the following best defines an "Artificial Intelligence System" according to the EU AI Act?

The provided answer accurately reflects the definition of an "Artificial Intelligence System" as outlined in the EU AI Act. According to the Act, such a system is characterized by its use of algorithms and techniques, particularly those related to machine learning, deep learning, and other forms of data processing, to generate outputs. This aspect emphasizes that the system is not limited to solely operating independently, but rather involves complex processes that require the application of advanced techniques for functionality.

The focus on generating outputs underscores the purpose of AI systems, which is to process input data and provide meaningful results, whether in decision-making, automation, or interacting with users. This capability distinguishes AI systems from simpler software, which may not utilize sophisticated techniques to derive insights or perform tasks.

In contrast, other options lack the core elements that define an AI system. For instance, the idea of software that operates without human intervention is too narrow and does not capture the essence of AI's reliance on data-driven methodologies. The notion of a manual system designed to enhance productivity does not align with the automated and intelligent processes associated with AI. Similarly, hardware used for data storage does not encompass the functionality and characteristics inherent to AI systems, which primarily revolve around software capabilities and their intelligent processing of information.
