Numerical approach for quantification of epistemic uncertainty
In the field of uncertainty quantification, uncertainty in the governing equations may assume two forms: aleatory uncertainty and epistemic uncertainty. Aleatory uncertainty can be characterised by known probability distributions whilst epistemic uncertainty arises from a lack of knowledge of probabilistic information. While extensive research efforts have been devoted to the numerical treatmen...
متن کاملEpistemic Uncertainty Quantification in Scientific Models
Chen, Xiaoxiao Ph.D., Purdue University, December 2014. Epistemic Uncertainty Quantification in Scientific Models. Major Professor: Dongbin Xiu. In the field of uncertainty quantification (UQ), epistemic uncertainty often refers to the kind of uncertainty whose complete probabilistic description is not available, largely due to our lack of knowledge about the uncertainty. Quantification of the ...
متن کاملComparison of Numerical Methods in Uncertainty Quantification
Abstract: This paper presents and compares the results obtained using several methods for Stochastic Computations, used in Uncertainty Quantification. We practically present the methods using a simple ODE model. The focus is on both intrusive and non-intrusive methods, namely the Monte Carlo method, along with methods based on generalized polynomial chaos(gPC) methodology. Moreover, we asses th...

متن کاملNumerical Probabilistic Analysis under Aleatory and Epistemic Uncertainty
This paper discusses Numerical Probabilistic Analysis (NPA) for problems under aleatory and epistemic uncertainty. The basis of NPA are numerical operations on probability density functions of the random values and probabilistic extensions. The numerical operations of the histogram arithmetic constitute the major component of NPA. The concepts of natural, probabilistic and histogram extensions ...
