Definition
A proposed graph of optimizers, evaluators, counter-metrics, auditors, and promotion gates governing how an AI system changes. One loop may optimize a target while another watches for regressions or checks whether the target still represents the real objective.
Distinguish it from nearby terms
An improvement loop changes one component and measures it. An improvement graph makes multiple interacting control and evidence relationships explicit. More nodes do not guarantee independence if they share the same blind spots.
Check your understanding
Identify which evaluator is outside the thing being optimized, which evidence is frozen, and what automatically reverts a harmful change.
