On the relationship between the knowledge model and the problem of pattern recognition

The article is devoted to the problem of pattern decomposition in solving the problem of pattern recognition. The problem of pattern decomposition is considered regardless of the recognition algorithms used. The only requirement is that the pattern recognition problem has a classical formulation. The article shows that without reference to the knowledge model, the decomposition of pattern cannot be performed within the framework of the recognition task itself, since it leads to a revision of the recognition task itself. In those cases, when the pattern recognition problem is preserved during decomposition, it may change in such a way that its solution in the decomposed form is not identical to the solution of the original pattern recognition problem.
