When solving any complex problems, a person widely uses "reasoning by analogy," "intuition," "informal approach," etc. The creation of machines that can solve various complex problems is currently hampered by the lack of programs that perform such poorly formalized operations. The main difficulty in the problem of recognition lies in the same area: how to find a principle on the basis of which some objects can be recognized as "similar" to each other? Therefore, advancement in the problem of recognition will help convey to machines not only "mechanical," but also "creative" human actions.
