Course objectives
The goal of the course is to acquaint students with actual trends in development and implementation of expert systems based on different types of vagueness and also with methods of softcomputing. Practical exercises acquaint students with used empty knowledge-based and/or expert systems with emphasis on integration of fuzzy approaches. Inseparable part of the exercises is also design of knowledge or expert basis of a fuzzy rule based expert system for a priori determined problem in given empty fuzzy rule based knowledge-based or expert system.
  • 1. Subjective knowledge and mental models, language modeling, conditional production rules, set of rules as language model, vagueness of the language model
    2. Vagueness of conditional rules formalized by means of probability level, expert systems with entropy such as MYCIN, EMYCIN and PROSPECTOR
    3. Probability-based rule-based expert systems - FEL-EXPERT
    4. Formalization of vagueness of language terms by means of fuzzy sets, basics of fuzzy mathematics, approximation of language models of fuzzy functions, fuzzification and defuzzification
    5. Fuzzy logic, language variable, interpretation of fuzzy logic functions, fuzzy relations, approximative derivation, fuzzy rule Modus Ponens
    6. Fuzzy approximation of multidimensional non-linear systems, approximative derivation based on Takagi-Sugeno rules
    7. Cognitive analysis of rule base of knowledges, consistency test, diversification of knowledge base, ternary graph
    8. Artificial neural multi-layer networks, adaptation procedures of ANN, fuzzy neural networks, identification of the fuzzy model Takagi-Sugeno
    9. Automatic methods of structural and parametric identification of rule-based fuzzy models, fuzzy clustering methods
    10. Basics of fuzzy regulation, linear regulators in case of feedback regulation, fuzzy regulators synthesis, Sugeno-based regulators
    11. Methods of structural and parametric optimalization of rule-based fuzzy models, optimalization methods based on evolution
    12. Real-time expert system, knowledge management, intelligent regulators, knowledge-based adaptation of structure and parameters of regulators
