Uncertainty phenomena and formalisms of their modeling in expert systems
Dragan Šaletić Dušan Velašević
Different types of uncertainty and their relations are pointed out in the paper. The short review of mathematical formalisms used for modeling uncertainty in expert systems is given. The difference between probability and fuzziness, expressed also in a formal mathematical manner, is shown. Conditions specifying applications of considered approaches to uncertainty modeling, are defined, thus making easier the modeling of uncertainty in expert and other systems of artificial intelligence. The possibilities of further research work in the domain are considered.
Key words: computer science, artificial intelligence, expert systems, uncertainty, fuzzy logic, probability, theory of rough sets. |
