Fuzzy sets fuzzy set hierarchy where_are_fuzzysets_used some of the operations on fuzzysets a comment on the range of membership values a fuzzy set is a mapping of a set of real numbers (x i) onto membership values (u i) that (generally) lie in the range [0, 1]in this fuzzy package a fuzzy set is represented by a set of pairs u i. The concept of fuzzy sets is one of the most fundamental and influential tools in computational intelligence fuzzy sets can provide solutions to a broad range of problems of control, pattern classification, reasoning, planning, and computer vision. Another way to describe reality more accurately is with the membership of fuzzy sets the difference between a binary set and a fuzzy set is that in a normal set every element is either a member or a non-member of the set here again, we see that it either has to be a or not-a. All information can be divided into one of two categories: certain and uncertain uncertain information can be further divided into two sub-categories: incomplete precise information that uses probability methods and imprecise information that uses the fuzzy set theory to give verbal statements a numerical clarity without losing imprecision.

A fuzzy set is a class of objects with a continuum of grades of membership such a set is characterized by a membership (characteristic) function which assigns to each object a grade of membership ranging between zero and one. Fuzzy set is a mathematical model of vague qualitative or quantitative data, frequently generated by means of the natural languagethe model is based on the generalization of the classical concepts of set and its characteristic function.

In this innovative approach to the practice of social science, charles ragin explores the use of fuzzy sets to bridge the divide between quantitative and qualitative methods paradoxically, the fuzzy set is a powerful tool because it replaces an unwieldy, fuzzy instrument—the variable, which establishes only the positions of cases relative to. 1 fuzzy sets: calibration versus measurement charles c ragin professor of sociology and of political science university of arizona tucson, az 85721 usa.
