The beginning of the neural networks history is connected with the "connectionist models" or "parallel distributed processing", that are considered in the publication in 1943 of McCulloch and Pitts. These scientists proposed general approaches and specific mathematical models of the biological neural networks and their components - neurons, that became fundamental in the artificial neural networks theory. These neurons were presented as models of the biological neurons and as conceptual components for circuits, that performed computational tasks. They used threshold elements with two stable states, which are called “McCallock-Pitts neurons" [1]. The task of developing models and systems, which are based on the threshold elements was so unusual and complex, that only in 1956 was appeared the first capable artificial neural network - Rosenblatt perceptron. Its demonstrated the possibility of creating technical patterns, based on the models of the human brain, for image recognition. However, further researches of perceptrons showed, that their usage in the recognition systems is associated with many difficulties. In 1969 Minsky and Papert published their book, in which they described the deficiencies of the perceptron model and showed their fundamental nature. The negative prognosis of the authoritative scientists caused a decline in the interest in neural networks, which lasted more than ten years, but in the 80's after some important theoretical results, the neural networks began to rebound. The renewed interest is reflected in many researches, the amounts of funding, the number of conferences and journals associated with neural networks [2,3]. At the same time, neurocomputing begins to develop, which allows solving problems from different areas of knowledge using neural networks, which are modelled on ordinary computers [4]. The machine interpretation of the neural network came into the world of Computer[...]

Methods of vibration treatment, vibration transporting, separation, adhesion, and hence the corresponding machines and equipment have been widely used in various industries [1-4]. Their implementation contributes to the intensification of various production processes, increases the level of mechanization of labor-intensive work, increases economic efficiency and productivity. With an increase in the intensity of production, the scope of application of vibrating machines expands, and new ones are created for various technological operations [1,4,5]. This is due to the simplicity of their designs, and in many cases, higher performance than that of conventional machines. Especially effective application of vibration equipment is in the chain of technological processes, which are associated with the processing of various friable mixtures, their dosage, mixing, separation, sealing, etc. [6,7]. In this case, along with the intensification of technological processes during the vibrational impact on the material, the quality of the final product improves: due to constant vibration, a high degree of separation of the mixture by its physical, mechanical or other properties is achieved. Despite the significant progress in the creation of a new and modernization of existing vibration equipment, theoretical studies related to the vibrational processes of friable media - sieve have not been properly developed due to the lack of satisfactory methods for analyzing these complex dynamic processes [8,9]. Above mentioned, on the one hand, led to the intensive introduction of vibration processes into production, on the other hand - it requires to change the basic dynamic characteristics of the working containers, and on this - the dynamics of the friable media, that is, using vibration machines of a controlled type [1,5,8,10-13]. For them, as a rule, there is no transition via the resonances of individual units and the machine as a whole, whi[...]
