In differential measurements of the $t\bar{t}b\bar{b}$ process, observables related to the b jets not originating from top quark decays are of special interest to probe the multi-scale QCD nature of the $t\bar{t}b\bar{b}$ process, and the description of the additional b jet radiation via different simulation tools. In order to access these additional b jets, identification algorithms have to be applied to determine which of the b jets recorded in the detector are the b jets of interest. This is achieved via a DNN-based method which will be highlighted in this article.
