On the Problem of Defuzzification in Computing With Regular Weighted Function

This paper deals with one problem that needs to be addressed in the emerging field known under the name “computing with perceptions”. It is the problem of describing, approximately, a given fuzzy set in natural language. This problem has lately been referred to as the problem of retranslation. An approaches for dealing with the retranslation problem is discussed in the paper, that is based on a pre-defined set of linguistic terms and the associated fuzzy sets. The retranslation problem is discussed in terms of two criteria—validity and informativeness.
