TL;DR: Experimental results are presented which indicate that more accurate clustering may be obtained by using fuzzy covariances, a natural approach to fuzzy clustering.
Abstract: A class of fuzzy ISODATA clustering algorithms has been developed previously which includes fuzzy means. This class of algorithms is generalized to include fuzzy covariances. The resulting algorithm closely resembles maximum likelihood estimation of mixture densities. It is argued that use of fuzzy covariances is a natural approach to fuzzy clustering. Experimental results are presented which indicate that more accurate clustering may be obtained by using fuzzy covariances.

TL;DR: Fuzziness is discussed in the context of multivalued logic, and a corresponding view of fuzzy sets is given.

TL;DR: An analysis is performed of the fuzzy logic controller which results in the identity between this controller and a multilevel relay, which is used in stability analysis.

TL;DR: It is shown in this paper that fuzzy set theory can be applied to scene analysis for considering the imprecise data and for employing approximate reasoning.
Abstract: A scene analysis system should be able to work with imprecise data and should integrate pieces of evidence collected from different knowledge sources. It is shown in this paper that fuzzy set theory can be applied to scene analysis for considering the imprecise data and for employing approximate reasoning.
