Abstract : A description of a self-organized system with positive feedback is presented. Results are given of investigating control methods by the order of self-teaching groups in the 'Alfa' system with one positive feedback. Methods of learning and self-teaching of groups of association cells of the system are discussed. It is shown that for a system with one positive feedback, the selection of signs for recognition of the given group of forms should be realized not only for usefulness and stability, but also for the sequence of signs or for the resolving power of the system for each two forms. In order that the group of association cells of the 'Alfa' system could relearn on any of the given forms, it is necessary that the minimum resolving power of the system be no less than unity at any given indicator adjustment of maximum voltage (IBN). Furthermore, it is necessary that the resolving power of each two forms differ at least by unity. The necessary minimum number of signs for the possibility of teaching and reteaching in the system is determined and it is shown that an increase in the number of positive feedbacks improves the selforganizing process in the system.
