TLDR
A procedure for validating models that involve linguistic variables, based upon the obtaining of the value of a truth variable, indicating how true a model is is introduced.Abstract:
This article introduces a procedure for validating models that involve linguistic variables. First we discuss Zadeh's extension principle for fuzzy sets. Then we discuss the concept of a linguistic truth variable. Using the concepts developed in these sections we present a methodology for validation models involving fuzzy and linguistic variables. This procedure is based upon the obtaining of the value of a truth variable, indicating how true a model is. This truth variable is obtained by fitting fuzzy data to our model.read more

On choosing between fuzzy subsets
TL;DR: The problem of selecting the highest grade of membership of fuzzy subsets of type 2 and of choosing the most truthful of a group of fuzzy propositions involve making a choice among fuzzy subset on the unit interval is proposed.

Linguistic recognition system based on approximate reasoning
Sankar K. Pal,Deba Prasad Mandal +1 more
TL;DR: A linguistic recognition system based on approximate reasoning has been described which is capable of handling various imprecise input patterns and of providing a natural decision, thus providing a low rate of misclassification as compared to the conventional two-state system.

On the design of a classifier with linguistic variables as inputs
Asoke Nath,Tsu-Tian Lee +1 more
TL;DR: It appears that the proposed design method for a classifier with linguistic variables as inputs may have potential applications in the areas of 'soft' sciences, including such fields as medicine and medical diagnostics.

The concept of a linguistic variable and its application to approximate reasoning—II☆
TL;DR: Much of what constitutes the core of scientific knowledge may be regarded as a reservoir of concepts and techniques which can be drawn upon to construct mathematical models of various types of systems and thereby yield quantitative information concerning their behavior.

Fuzzy logic and approximate reasoning
TL;DR: F fuzzy logic is used in this paper to describe an imprecise logical system, FL, in which the truth-values are fuzzy subsets of the unit interval with linguistic labels such as true, false, not true, very true, quite true, not very true and not very false, etc.

A fuzzy-algorithmic approach to the definition of complex or imprecise concepts
TL;DR: It may be argued, rather persuasively, that most of the concepts encountered in various domains of human knowledge are, in reality, much too complex to admit of simple or precise definition.
