Rule Acquisition Based on λ Approximated Fuzzy Rough Set and Its Application
In this paper, the concepts of λ approximated fuzzy rough set and its approximation capacity are defined as well as the inclusion degree of the fuzzy sets on the universe of discourse U, aimed at the problem that not all of the vague knowledge in knowledge warehouse can always be the weak vague partition of U. The problem of fuzzy decision-making rule acquisition is discussed according to the defined concepts,the approach about fuzzy decision-making information system is given by an example, the results shows the approach is effective.
