The Stratic Defuzzifier for discretised general type-2 fuzzy sets

Abstract Stratification is a feature of the type-reduced set general type-2 fuzzy set, from which new technique for defuzzification, Stratic Defuzzification, may be derived. Existing defuzzification strategies are summarised. The stratified structure described, after Defuzzifier presented and contrasted experimentally accuracy efficiency with both Exhaustive Method Defuzzification (to benchmark accuracy) ? -Planes/Karnik–Mendel Iterative Procedure strategy, employing 5, 11, 21, 51 101 -planes. shown to much faster than Defuzzifier.
