HUMAN IN THE LOOP— ORIGIN, MEANING & USAGE

Human In The Loop A system design where a human must review or approve an AI's output before it takes effect, distinct from human verification by being a structural safeguard built into a workflow rather than a one-time identity check.

Origin:Standard ML-industry terminology for systems that deliberately keep a human reviewer in the decision loop, now spreading into general internet vocabulary as AI automation raised the stakes of unattended errors.
