Development of systematic uncertainty-aware neural network trainings for binned-likelihood analyses at the LHC / CMS Collaboration
We propose a neural network training method capable of accounting for the effects of systematic variations of the data model in the training process and describe its extension towards neural network multiclass classification. [...]
