A direct proof of the existence of \nu _\mu \rightarrow \nu _\tau oscillations is important. This proof can be obtained by an observation of the production of taons in charge current reactions \nu _\tau + N \rightarrow \tau + X. The influence of \tau polarization on the characteristics of the CC events and on the efficiency of their selection is discussed. The neural network method is used to select \tau leptons produced in \nu _\tau interactions.
