Performance of an AI system

The ability of an AI system to achieve its intended purpose. Performance is therefore measured against the intended purpose, not against a standalone technical score.

What this object links to

Every relation appears below as a path: from the source with its locator, through the conditions and exceptions of the object carrying the relation, to the consequence. A locator belongs to a statement in the data and not to a relation, so the source is the source anchor of the carrying object.

What this object states

Official fact

Attributable to a named primary source, with a locator. Where they differ, the official source prevails.

Article 3(18) defines performance of an AI system as the ability of an AI system to achieve its intended purpose.

Our interpretation

Our own reading. It can change without the law changing, and it is not the position of a supervisory authority.

The definition ties performance firmly to the intended purpose in point 12. An accuracy of 94 percent is therefore no answer to whether the system performs, as long as it is not established what it is meant for and for which group of people that score holds. A model that scores well on average but performs structurally worse for a subgroup does not achieve the intended purpose for that group. That is exactly what Article 15 on accuracy and robustness and Article 10 on data quality target.

Recommended step

A practical step we consider appropriate. Not an obligation following from the Regulation.

For each AI system, record which performance metrics you use, which threshold is acceptable for the intended purpose, and how those metrics break down per relevant subgroup. Repeat the measurement periodically and retain the results, so you can demonstrate performance drift before a supervisory authority asks.
