Abstract. The methods of data complexation are proposed. For a limited number of channels, they allow obtaining the maximum possible amount of available information. Along with the reducers of degrees of freedom, discriminators of degrees of freedom are proposed to be used, which enables all the channels, in accordance with their current informativeness, to take part in making a cooperative decision.

Keywords: synergetics, data transmission channels, degrees of freedom, reducer, discriminator, mathematical statistics, Bayesian approach, small sample.
