Measuring Uncertainty with Imprecision Indices
The paper is devoted to the investigation of imprecision indices, introduced in [8]. They are used for evaluating uncertainty (namely imprecision), which is contained in information, described by fuzzy (non-additive) measures, in particular, by lower and upper probabilities. We argue that there exist various types of uncertainty, for example, randomness, investigated in probability theory, impr...
متن کاملImprecision in Engineering Design Imprecision in Engineering Design
A technique to perform design calculations on imprecise representations of parameters has been developed and is presented. The level of imprecision in the description of design elements is typically high in the preliminary phase of engineering design. This imprecision is represented using the fuzzy calculus. Calculations can be performed using this method, to produce (imprecise) performance par...
متن کاملRepresenting parametric probabilistic models tainted with imprecision
Numerical possibility theory, belief function have been suggested as useful tools to represent imprecise, vague or incomplete information. They are particularly appropriate in uncertainty analysis where information is typically tainted with imprecision or incompleteness. Based on their experience or their knowledge about a random phenomenon, experts can sometimes provide a class of distribution...
متن کاملImprecision and Spatial Uncertainty
Geographic information systems date from the 1960s, when computers were mostly seen as devices for massive computation. Very significant technical problems had to be solved in those early days: how did one convert the contents of a paper map to digital form (by building an optical scanner from scratch); how did one store the result on magnetic tape (in the form of a linear sequence of records r...
متن کاملScale-imprecision space
It is argued that image measurements should satisfy two requirements of physical plausibility: the measurements are of non-zero scale and non-zero imprecision; and two required invariances, nothing is lost by expanding the image and nothing is lost by increasing the contrast of the image. A model of measurements satisfying these constraints, based on blurring the graph of the incident luminance...
