A decision rule of randomized parameters and probability density function (PDF) is formed, which is determined by the solution of the problem of the functional entropy linear programming. A procedure for \u201c2\u201d-soft classification is developed, consisting of the computer simulation of the randomized decision rule with optimal entropy PDF parameters.
