    A fuzzy-logic-based approach dealing with temporal uncertainty is presented. Both imprecision of temporal measurements and uncertain temporal knowledge are taken into consideration. Various causes of temporal uncertainty or fuzziness are discussed. On the basis of fuzzy set and possibility theory, each temporal uncertainty is represented in terms of possibility distributions. Definitions of tempor... View full abstract»

    The problem of how to build expert systems for recognizing vague or incomplete images is addressed. The focus is on the partial match and estimation of supports, per degree of similarity, of each possible option. Two methods were used: a voting model interpretation of fuzzy sets to classify the objects, and the iterative assignment algorithm to obtain the support. To test the learning capabilities...

    Signal decision models based on Dempster-Shafer and fuzzy set theories were developed to facilitate the implementation of a rule-based interpretation system for sensory evoked potential waveforms. The models do not require a priori probabilities, and they provide measures of uncertainty. The two models were applied to a set of brainstem auditory evoked potential waveforms. Both had lower absolute ... View full abstract»
