COGNITIVE FUNCTIONS AS THE ADEQUATE INSTRUMENT FOR THE FORMAL SUBMISSION OF CAUSE AND EFFECT ASSOCIATIONS

abstract 0631009001 issue 63 pp. 1 – 23 27.11.2010 ru 2220
In this article application of the method of computerized system-cognitive analysis and its programmatic tooling – system "Eidoses" for detection of cause and effect associations from the trial-and-error data is considered. In the capacity of a toolkit for the formal submission of cause and effect associations cognitive functions are tendered. Cognitive functions represent many-valued interval functions of many arguments in which one various value of function in a various degree match to various value of arguments, and the quantitative standard of this correspondence appears to be the knowledge, i.e. the information about cause and effect associations in the trial-and-error data, beneficial to a goal achievement

COGNITIVE FUNCTIONS AS A GENERALIZATION OF THE CLASSICAL CONCEPT OF FUNCTIONAL DEPENDENCE ON THE BASIS OF INFORMATION THEORY IN ASC-ANALYSIS AND SYSTEM FUZZY INTERVAL MATHEMATICS

abstract 0951401007 issue 95 pp. 122 – 183 30.01.2014 ru 1871
This article briefly reviews the classical concept of functional dependence in mathematics, determines the limitations of this concept for adequate modeling of reality and formulates the problem, consisting in search of such generalization of the concept of func-tions, which is more suitable for the adequate reflec-tion of causal relationships in the real domain. Also, it discusses theoretical and practical solving the prob-lem, consisting in: (a) we suggest the universal method of calculating the amount of information in the value of argument about the meaning of the function, i.e. cognitive functions which is independent from the subject area; b) we offer software tools: Eidos intelli-gent system, allowing in practice to carry out these calculations, i.e. to build cognitive functions based on a fragmented noisy empirical data of high dimension. We also offer the concepts of nonreducing, partially and completely reduced direct and inverse, positive and negative cognitive functions and the method of formation of reduced cognitive function, which is a generalization of known weighted least-squares meth-od on the basis of observation the amount of infor-mation in the values of the argument about the values of the functions accounting

CLIMATIC CHANGES IN THE BLACK SEA REGION AND ELABORATION OF STRATEGY FOR ITS SUSTAINABLE DEVELOPMENT

abstract 0901306016 issue 90 pp. 258 – 293 30.06.2013 ru 1659
In this article, we consider some aspects of regional development under changing climatic conditions. Further, we discuss trends and in global and regional climate in the past century and scenarios of climatic changes up to the end of the current century. The system of measures is suggested for transition to sustainable development of Russian Black Sea Coast. The conclusion is made that elaboration and correction of the regional sustainable development strategy requires wide spreading of information about climatic changes, environmental, economical and demographic conditions in the region

CLIMATE-ECONOMIC MODEL WITH ENDOGENOUS CAPITAL DEPRECIATION RATE UNDER UNCERTAINTY OF TEMPERATURE PROJECTIONS

abstract 1041410089 issue 104 pp. 1206 – 1214 30.12.2014 ru 1034
A simple climate–economic model based on the AK model of economic growth with the endogenous depreciation rate linear in temperature and on the exogenous climate scenario with temperature linear in time is considered. The analytical solution of the model is obtained. The uncertainty of temperature projections is introduced in the model, and the moments of model state variable are calculated analytically. Numerical examples are provided

CLARIFICATION OF A MODEL OF A BALANCING ROBOT BY LOGICAL AND EMPIRICAL METHODS

abstract 1211607011 issue 121 pp. 336 – 356 30.09.2016 ru 665
This work studies the mathematical model of the object “inverted pendulum” on the example of the unstable electromechanical devices which is balancing robot on wheel couple. Unfortunately, many details of object model are unknown. Logical and empirical method offers hypotheses about the difference between the actual object model from its mathematical approximation based on logical analysis with subsequent refinement of this model and testing of the hypothesis with modeling of the systems with the updated model. As a result, the amendments to the model have been found containing nonlinear components. With the help of these amendments, the dynamic characteristics of the actuator, filters, friction and the tendency of the object to fluctuations are better taken into account

CHARACTERIZATION OF AVERAGE VALUES BY MEANS OF MEASUREMENT SCALES

abstract 1341710070 issue 134 pp. 853 – 883 29.12.2017 ru 393
According to measurement theory, statistical data are measured in various scales. The most widely used ordinal scale, scales of intervals and relations. Statistical methods of data analysis should correspond to the scales in which the data is measured. The term "correspondence" is specified with the help of the concepts of an adequate function and an allowable scale transformation. The main content of the article is a description of the average values that can be used to analyze data measured in the ordinal scale, interval and relationship scales, and some others. The main attention is paid to the means for Cauchy and the means for Kolmogorov. In addition to the mean, from this point of view, polynomials and correlation indices are also analyzed. Detailed mathematical proofs of characterization theorems are given for the first time in scientific periodicals. It is shown that in the ordinal scale there are exactly n average values, that can be used, namely, n order statistics. The proof is represented as a chain of 9 lemmas. In the scale of intervals from all Kolmogorov means, only the arithmetic mean can be used. In the scale of relations from all the Kolmogorov means, only the power means and the geometric mean are permissible. The kind of adequate polynomials in the relationship scale is indicated

CHAOS AND ORDER OF DISCRETE SYSTEMS IN LIGHT OF SYNERGETIC INFORMATION THEORY

abstract 0470903008 issue 47 pp. 96 – 129 31.03.2009 ru 11193
Estimation of chaos and order in structure of electronic systems of atoms, protein molecules, webs of spiders, poetic products is done with the help of synergetic information theory. Existence of statistical rule of structural organization in nature is expected. This rule directs evolution of discrete system towards balance of chaos and order.
