Estimating information amount under uncertainty: algorithmic solvability and computational complexity
Sometimes, we know the probability of different values of the estimation error ∆x def = e x− x, sometimes, we only know the interval of possible values of ∆x, sometimes, we have interval bounds on the cdf of ∆x. To compare different measuring instruments, it is desirable to know which of them brings more information – i.e., it is desirable to gauge the amount of information. For probabilistic u...
متن کاملCalculation of Measurement Uncertainty Using Prior Information
We describe the use of Bayesian inference to include prior information about the value of the measurand in the calculation of measurement uncertainty. Typical examples show this can, in effect, reduce the expanded uncertainty by up to 85 %. The application of the Bayesian approach to proving workpiece conformance to specification (as given by international standard ISO 14253-1) is presented and...

15 صفحه اولAmount of Information 1 Running head: AMOUNT OF INFORMATION Effects of Amount of Information on Judgment Accuracy and Confidence
When a person is makes a judgment and assesses confidence, what is the effect of receiving more judgment-relevant information? Following up prior research on belief updating judgments (Oskamp, 1965; Slovic, 1973), we demonstrated that the predictive accuracy of experts did not improve but their confidence climbed steadily as they received more information about the target event. Our findings sh...
متن کاملEstimating Information Amount under Interval Uncertainty: Algorithmic Solvability and Computational Complexity
In most real-life situations, we have uncertainty: we do not know the exact state of the world, there are several (n) different states which are consistent with our knowledge. In such situations, it is desirable to gauge how much information we need to gain to determine the actual state of the world. A natural measure of this amount of information is the average number of “yes”-“no” questions t...
