Graduated substrata

摘要

A graduated substratum is a graphic representation corresponding to the support of a discrete fuzzy set: It is a set of granulations whose diameters are proportional to the membership values of the respective elements they represent. It is used to represent graphically the notions (relation, construction of a relation, application of the mapping rule) developed by Zadeh to apply fuzzy set theory to pattern classification. A connection with neurophysiology is proposed in the form of the identification: Fuzzy set &z.tbnd; Graduated substratum  Activated neural population.
