Family of 2-simplex cognitive tools and their application for decision-making and its justifications
Urgency of application and development of cognitive graphic tools for usage
in intelligent systems of data analysis, decision making and its justifications
is given. Cognitive graphic tool "2-simplex prism" and examples of its usage
are presented. Specificity of program realization of cognitive graphics tools
invariant to problem areas is described. Most significant results are given and
discussed. Future investigations are connected with usage of new approach to
rendering, cross-platform realization, cognitive features improving and
expanding of n-simplex family.Comment: 14 pages, 6 figures, conferenc
Bases of intelligent system construction of the pipeline technical condition diagnostics
The urgent of creating the intelligent systems for revealing different kinds of regularities and decision-making in the problem area of pipeline technical condition diagnostics is considered. The technical condition diagnostics of pipeline is strongly dependent on the pipeline parameters, hydrodynamic characteristics of the pipeline-transported substance and that of environment (ambient medium). The advisability for the construction of the intelligent system for the pipeline technical condition diagnostics (IS PTCD) based on intelligent instrumental software (IIS) IMSLOG ambient medium, aimed at revealing different types of regularities in data and knowledge, decision-making and its justification with using cognitive tools, is shown. The matrix way of data and knowledge representation in the problem area and the main stages of IS PTCD constructing based on IIS IMSLOG IS PTCD are given. This will allow to reveal different types of regularities in data and knowledge on the base of the features that influence on the technical condition of the pipeline and, as well as make-decisions of the diagnostic and repair-prophylactic character. IS PTCD is essentially useful for the engineers in the problem area of pipeline-transported substance for decision-making and its justification with using cognitive tools, as well as for research activities and also for student training programs in the problem area
Matrix model of data and knowledge presentation to revealing regularities of the fluid flow regime in a pipeline based on hydrodynamics parameters
The study offers an original solution to one of the problems of hydrodynamics, namely revealing the regularities in the flow regime of fluid in a pipeline depending on the hydrodynamic parameters. The solution is based on using the intelligent system of the regularities revealing and decision-making. For the first time, a matrix model of data and knowledge representation (MM) is used for these purposes in the form of two matrices: descriptions of the fluid state in the space of characteristic features of hydrodynamics (pressure, velocity, temperature, and others); its rows are associated with various combinations of characteristic features values, and distinguishing of the diagnostic type, whose rows are associated with the corresponding rows of the description matrix, and its columns are associated with the two classifying features. The first classifying features takes four values corresponding to four fluid flow regimes, and the second classifying features takes three values only for the turbulent flow regime value from the first classifying features
Foundation of the Construction of Mixed Diagnostic Tests in Systems for Quality Control of Education
Application of Learning and Testing Intelligent System with Cognitive Component Based on Mixed Diagnostics Tests
Relevance of computer based learning and testing of students is discussed. Learning and testing intelligent system (LTIS) is proposed for learning, testing, learning results and dynamics assessment. LTIS is aimed at professional and personal skills and abilities estimation, and also for designing learning trajectory of courses. A new assessment approach called mixed diagnostic tests (MDT) for LTIS construction is discussed. Analysis of the effective MDT and their implementation are proposed. The cognitive component based on 3-simplex and 2-simplex prism is suggested. MDT reduces both time and cost expenses for organization and control of the educational process. Since MDT may replace consultant function of teacher, the proposed approach is promising in the blended learning. The decision-making results are justified via cognitive component
Data and knowledge base on the basis of the expanded matrix model of their representation for the intelligent system of road-climatic zoning of territories
An extended matrix model of data and knowledge representation on the investigated area, as well as a matrix model of data representation on the territory under investigation, are proposed for the intelligent system of road-climatic zoning of territories (RCZT) - the main information technology of RCZT. A part of the West Siberian region has been selected as the investigated territory. The extended matrix model of knowledge representation is filled out by knowledge engineers with participation of highly qualified experts in the field of RCZT. The matrix model of data representation on the territory under investigation is filled out by persons concerned in RCZT of the motor-roads management system
