Perceptual Computing: Aiding People in Making Subjective Judgments
Jerry Mendel
Explains for the first time how "computing with words" can aid in making subjective judgments
Lotfi Zadeh, the father of fuzzy logic, coined the phrase "computing with words" (CWW) to describe a methodology in which the objects of computation are words and propositions drawn from a natural language. Perceptual Computing explains how to implement CWW to aid in the important area of making subjective judgments, using a methodology that leads to an interactive device—a "Perceptual Computer"—that propagates random and linguistic uncertainties into the subjective judgment in a way that can be modeled and observed by the judgment maker.

Use uncertainty measures to quantify linguistic uncertainties

Compute the subsethood of one IT2 FS in another such set
-
Aggregate disparate data, ranging from numbers to uniformly weighted intervals to nonuniformly weighted intervals to words
-
Aggregate multiple-fired IF-THEN rules so that the integrity of word IT2 FS models is preserved
Free MATLAB-based software is also available online so readers can apply the methodology of perceptual computing immediately, and even try to improve upon it. Perceptual Computing is an important go-to for researchers and students in the fields of artificial intelligence and fuzzy logic, as well as for operations researchers, decision makers, psychologists, computer scientists, and computational intelligence experts.
