This paper describes an application of a neural network approach to standard model Higgs search in the associated production ttH with H->bb. Neural network model with a special type of data flow is used to separate ttjj background from H->bb events. Randomly generated networks are trained and genetic algorithms are used to tune their performance. Our results show that NN approach is applicable to H-boson detection and can be used to emphasize difference of M_bb distribution for events accepted by filter.
