Epistemic and Aleatoric Uncertainty in Modeling
Volume 8: 22nd Reliability, Stress Analysis, and Failure Prevention Conference; 25th Conference on Mechanical Vibration and Noise, 2013One major difficulty that exists in reconciling model predictions of a system with experimental measurements is assessing and accounting for the uncertainties in the system. There are several enumerated sources of uncertainty in model prediction of physical phenomena, the primary ones being: 1) Model form error, 2) Aleatoric uncertainty of model ...

Epistemic Uncertainties in Decision Making
24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 2, 2005The present paper reviews and outlines the interpretation of uncertainties with a view to the various different categorizations introduced in the literature. A framework is then presented for risk based decision making taking basis in the Bayesian decision theory and recent methodical developments in risk assessment.

The Role of Epistemic Uncertainty in Risk Analysis
2010The notion of uncertainty has been a controversial issue for a long time. In particular the prominence of probability theory in the scientific arena has blurred some distinctions that were present from its inception, namely between uncertainty due to the variability of physical phenomena, and uncertainty due to a lack of information.

Aleatory and Epistemic Uncertainty Quantification
2015In this paper, an effort has been made to combine aleatory and epistemic uncertainties in risk models. We have combined probabilistic distributions, generalized fuzzy numbers, and completely generalized interval valued fuzzy numbers.

Epistemic Uncertainty Modeling: The-state-of-the-art
2015This paper is about the state-of-the-art of epistemic uncertainty modeling from subjective probability (Thomas Bayes) to fuzzy measures (Michio Sugeno).

The anxious inquirer : emotions and epistemic uncertainty
L'enquêteur anxieux : émotions et incertitude épistémique En épistémologie, des développements récents ont conduit à considérer que les états affectifs sont des facteurs pertinents dans l'étude de la connaissance. Je me concentrerai précisément sur l'attitude épistémique du doute, dans la mesure où elle est liée à la réaction ...openaire +2 more sources
Multi-objective Optimization of Problems with Epistemic Uncertainty
2005Multi-objective evolutionary algorithms (MOEAs) have proven to be a powerful tool for global optimization purposes of deterministic problem functions. Yet, in many real-world problems, uncertainty about the correctness of the system model and environmental factors does not allow to determine clear objective values.

Reasoning with uncertainty and epistemic modals
2014My dissertation presents complementary views of reasoning with uncertainty and communicating in situations of reasoning with uncertainty. Reasoning with uncertainty proceeds from the possibilities an agent takes as options, rather than those that are merely consistent with her information or that she has positive credence in.
