'''Human-in-the-loop''' or '''HITL''' is used in multiple contexts. It can be defined as a model requiring human interaction.<ref>"DoD Modeling and Simulation (M&S) Glossary", DoD 5000.59-M, [[United States Department of Defense|DoD]], January 1998 {{cite web |url=http://www.dtic.mil/whs/directives/corres/pdf/500059m.pdf |title=Directives Division |accessdate=2009-04-22 |url-status=dead |archiveurl=https://web.archive.org/web/20070710104756/http://www.dtic.mil/whs/directives/corres/pdf/500059m.pdf |archivedate=2007-07-10 }}</ref><ref>Karwowski, Waldemar, ''[https://books.google.com/books?id=3hkbHSV81XMC&pg=PA2407 International encyclopedia of ergonomics and human factors]'', {{ISBN|0-415-30430-X}}, 9780415304306, [[CRC Press]], 2006</ref> HITL is associated with [[modeling and simulation]] (M&S) in the [[live, virtual, and constructive]] [[Taxonomy (general)|taxonomy]].

==Machine learning==

In machine learning, HITL is used in the sense of humans aiding the computer in making the correct decisions in building a model.<ref name=medium /> HITL improves machine learning over random sampling by selecting the most critical data needed to refine the model.<ref name=schizophrenia>{{cite journal|title=Improving the Applicability of AI for Psychiatric Applications through Human-in-the-loop Methodologies|author1=Chelsea Chandler|author2=Peter W Foltz|author3=Brita Elvevåg|date=26 May 2022|journal=Schizophrenia Bulletin|volume=48|issue=5|pages=949-956|doi=10.1093/schbul/sbac038}}</ref>
