Abstract: (PoS)
An observation of Higgs boson production in association with a top quark pair (ttH\mathrm{t \overline{t}H}) is a key outstanding measurement of the LHC programme. Boosted Decision Trees are vital for the search of ttH\mathrm{t \overline{t}H}, playing a role in event reconstruction and discriminating signal from a large background. The use of BDTs in the ATLAS search for ttH\mathrm{t \overline{t}H}, Hbb\mathrm{H \rightarrow b \overline{b}} is presented for the preliminary results on the s=13\sqrt{s} = 13 TeV, 13.213.2 fb1^{-1} dataset.
