Human-in-the-Loop

Human-in-the-loop refers to an automated system design where a human operator remains an active participant in decision-making and retains direct control, intervening when necessary.

TECHNICAL DEFINITION

Human-in-the-loop (HITL) describes a system architecture where a human operator maintains continuous oversight and direct control over an autonomous or unmanned system, actively making or approving critical decisions and intervening in real-time to ensure mission success and adherence to rules of engagement in military and defense applications.

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.
