 Machine Learning in Top Physics in the ATLAS and CMS Collaborations / Keicher, Philip Daniel (Hamburg U.) /ATLAS and CMS Collaborations Machine learning is essential in many aspects of top-quark related physics in the ATLAS and CMS Collaborations. This work aims to give a brief overview over current applications in the two collaborations as well as on-going studies for future applications.\footnote{Copyright 2023 CERN for the benefit of the ATLAS and CMS Collaborations.
