Uncertainty and Sensitivity Assessments of GPS and GIS Integrated Applications for Transportation

Sungchul Hong, Alan Vonderohe
2014 Sensors  
However, for the distance-based computational model, output information has a different magnitude of uncertainties, depending on position uncertainties in input data.  ...  In the methods, an error model and an error propagation method form a basis for formulating characterization and propagation of uncertainties.  ...  Author Contributions This paper is based on a research for my Ph.D. dissertation, and this research was conducted under guidance of Prof. Alan P. Vonderohe.  ...

Bayesian models: the structure of the world, uncertainty, behavior, and the brain

Iris Vilares, Konrad Kording
2011 Annals of the New York Academy of Sciences  
Experiments on humans and other animals have shown that uncertainty due to unreliable or incomplete information affects behavior.  ...  This formalization results in a wide range of Bayesian models that derive from assumptions about the world, and it often seems unclear how these models relate to one another.  ...  We also want to thank Hugo Fernandes and Mark Albert for helpful comments on the manuscript.  ...

Testing Links Among Uncertainty, Affect, and Attitude Toward a Health Behavior

Timothy K. F. Fung, Robert J. Griffin, Sharon Dunwoody
2018 Science communication  
It uses data from a longitudinal study (n = 334) of people's reactions to the risks of eating contaminated fish from the Great Lakes, which employed the Risk Information Seeking and Processing model, and  ...  Findings support the expanded model and indicate that worry and anger strongly influenced uncertainty judgments, but anger and worry influenced attitudes toward fish avoidance and information insufficiency  ...  However, while perceived threat to future generations had a significant positive impact on worry, its impact on anger was negligible.  ...

The improvement of uncertainty measurements accuracy in sensor networks based on fuzzy dempster-shafer theory

Ehsan Azimirad, Seyyed Reza Movahhed Ghodsinya
2020 IJAIN (International Journal of Advances in Intelligent Informatics)  
In this paper, a model-based uncertainty is presented in the air defense system based on the Fuzzy Dempster-Shafer Theory to measure uncertainty and its accuracy.  ...  In literature, there are some theories that state and model uncertainty in the information. One of the new methods is the Fuzzy Dempster-Shafer Theory.  ...  No additional information is available for this paper.  ...

The Generalization of Prior Uncertainty during Reaching

H. L. Fernandes, I. H. Stevenson, I. Vilares, K. P. Kording
2014 Journal of Neuroscience  
Bayesian statistics defines how new information, given by a likelihood, should be combined with previously acquired information, given by a prior distribution.  ...  In particular, we look into how the first two moments of the prior-the mean and variance (uncertainty)-generalize.  ...  A-D, Model comparison for Models T and VF for Uncertainty (A, B) and for Mean (C, D).  ...

Onto computing the uncertainty for the odometry pose estimate of a mobile robot

Josep M. Mirats Tur
2007 2007 IEEE Conference on Emerging Technologies & Factory Automation (EFTA 2007)  
In a previous work, a general method to obtain the uncertainty in the odometry pose estimate was proposed.  ...  Here, with the aim of assessing the generality of the method, the general formulation is particularized for a given differential driven robot.  ...  This is not fully consistent with the experiment run, because only one source of position information has been used to compute the position of the robot, so there is no extra information so as to decrease  ...

Uncertainty and Value of Information in Risk Prediction Modeling [article]

Mohsen Sadatsafavi, Tae Yoon Lee, Paul Gustafson
2021 arXiv   pre-print
We apply Value of Information methodology to evaluate the decision-theoretic implications of prediction uncertainty.  ...  Results: With a sample size of 1,000 and at the pre-specified threshold of 2% on predicted risks, the gain in net benefit by using the proposed and the correct models were 0.0006 and 0.0011, respectively  ...  Nonetheless, Value of Information in decision analysis is justified based on the working assumption that a model that is good enough for calculating net benefit is also good enough for quantifying uncertainty  ...

Shin Funada, Jun Suzuki
2020 arXiv   pre-print
We investigate the uncertainty relation for estimating the position of one electron in a uniform magnetic field in the framework of the quantum estimation theory.  ...  Two kinds of momenta, canonical one and mechanical one, are used to generate a shift in the position of the electron.  ...  Hiroshi Nagaoka for the invaluable discussion and suggestion. We would also like to thank anonymous referees for constructive discussions to improve the manuscript.  ...

J. Florian Wellmann, Mark Lindsay, Jonathan Poh, Mark Jessell
2014 Energy Procedia  
Several stochastic approaches have recently been developed to evaluate uncertainties in 3-D geological models based on imprecise geological data.  ...  We present here a method to enable automatic checks of models based on reliability filters encapsulating aspects of geological knowledge.  ...  In the example case of a model representing a graben structure, constraints based on additional information (min/max position and thickness of a layer) and on the geological evolution of an area (type  ...

Uncertainty and Political Perceptions

R. Michael Alvarez, Charles H. Franklin
1994 Journal of Politics  
Next, we estimated similar models examining the uncertainty responses for the Senator's issue positions. One problem for estimation of the response models is the presence of selection bias.  ...  For example, to place a moderate on an issue scale, the respondent needs a good deal of information -but not so for an extremist.  ...

1994 Procedings of the British Machine Vision Conference 1994  
This work proposes a methodology for the analysis of the uncertainty in the localization of objects when considering uncertain image data, camera and object geometry parameters.  ...  At the end of the process, a better estimate of the object pose with its uncertainty is given along with a new estimate of the used uncertain object features and the camera parameters.  ...  The authors want to thank David Wren and Andrew Fitzgibbon for proofreading the final document.  ...

Visualisation of Spatial Data Uncertainty. A Case Study of a Database of Topographic Objects

Ślusarski, Jurkiewicz
2019 ISPRS International Journal of Geo-Information  
Fill grain density and contour crispness were employed to represent the positional uncertainty for surface objects.  ...  The positional uncertainty for point objects was presented using visual variables, object fill with hue colour and lightness, and glyphs placed at map symbol positions.  ...  Data quality information is often generated and visualised using a scale for which the detail level of data uncertainty features presentation is optimised.  ...
