Human-on-the-Loop

Human-on-the-Loop describes an automated system where a human operator must explicitly approve or manually execute every critical decision or action, maintaining direct control throughout the process.

TECHNICAL DEFINITION

Within unmanned systems and autonomy in military applications, "Human-on-the-Loop" signifies a control paradigm where human operators retain explicit authority and direct intervention for every critical decision or action, actively approving or executing steps suggested by the autonomous system to ensure continuous human oversight and prevent fully independent machine execution.

BACKGROUND

Human-in-the-loop (HITL) is used in multiple contexts. It can be defined as a model requiring human interaction. HITL is associated with modeling and simulation (M&S) in the live, virtual, and constructive taxonomy. HITL, along with the related human-on-the-loop, are also used in relation to lethal autonomous weapons. Further, HITL is used in the context of machine learning.It is also used in conversational AI to manage complex interactions that require human empathy.
