Learn in the textbookHow AI Works: Transparency and Human Involvement
DefinitionHuman-in-the-loop (ヒューマンインザループ) is a mechanism that, instead of leaving processing entirely to the AI, builds human checks and decisions into the processing flow.
ExplanationFor example, a person reviews a proposal from the AI, approves it for execution if it is sound, and sends it back with corrections if not. With people stepping in at key points, AI errors and bias are stopped before anything is executed, and it is clear who made each decision and who is responsible.
AnalogyIt resembles approval inside a company, where a manager reads and signs off on a document a staff member drafted before it goes out.
Memory hookThe Japanese term simply writes the English "Human in the loop" in katakana. Picture a human standing inside the loop.
