Dynamic Model of Semantic Information Signal Processing

The article deals with the mathematical modeling of the regularism of thought processes based on the concept of ORASTA, consisting of a controller operator (OR) and an active contextual environment of regulation with a temporary constant (active system with time average – ASTA). Associative regulatory mechanisms of the thought process are considered on the basis of the developed systems of functional differential equations with delay, taking into account time relationships, cooperative processes and feedbacks in the regulation system. The existence of trivial and non-trivial equilibrium positions at certain ranges of parameters is revealed; stability of the rest regime in the absence of non-trivial equilibrium positions; the existence of stable and complex oscillatory modes of operation, which are important for analyzing the nature of the occurrence, development and deformation of the oscillatory background during the implementation of information processes in the activity of systems capable of thinking independently in the case of various external and internal signals. The developed equations of the regulatory mechanisms of paired associative phenomena in consciousness, taking into account the coupling of cognitive self-organizing processes, can be used for safe communication methods.
