Neural network (NN) model with a special type of data flow is used to separate ttjj background from H-->bb events. A genetic algorithm principles are used to tune parameters of NN in order to optimize the final NN performance. Our results show that NN filters can be used to emphasize shape of M_bb distribution for events accepted by filter. This improvement can be used as a criterion of existence of Higgs boson decay in considered data.
