Non-Deterministic System

A system or aspects of a system where decisions are derived from complex sensor and processing algorithms and / or involve machine learning (e.g., emergency intervention systems, advanced driver assistance systems, and artificial intelligence route planning). It may not be possible to establish an integrity level / performance level rating (e.g., MPL / PL / SIL) when using these systems.
