It is argued that mixtures of experts are often insightful for describing model discrepancy and ways in which the computer model can be improved.
The ultimate goals are to construct fragility models for various mitigation options accounting for uncertainties due to model discrepancy and experimental error and to determine the most cost-effective option under a potential hurricane in terms of aggregate loss estimates based on total probability of failure.
In this study, the variances of the model discrepancy and observational uncertainty are specified to be constants, and we consider a single model output.

Lengthen the lens and the focus gets blurred by model discrepancies and uncertainty, observation error, and the complex physics of weather.
This clearly highlights the need for global ocean observations of precipitation in different large-scale regimes to better understand underlying causes for model discrepancies and to help improve model parameterizations of precipitation processes.
Bayarri et al. [5] assessed the uncertainties in a traffic simulation modeling arising from multiple sources: randomness in the simulator, statistical variability in estimating and calibrating input parameters, inaccurate data and model discrepancy.
This is not a strength of standard approaches to the statistical analysis of computer models where a certain "best input" assumption is usually made and model discrepancy is often described through a stationary Gaussian process prior on the discrepancy function.
This paper proposes a new robust CEDO model for Bayesian calibration with field response and incorporates various sources of model uncertainty such as surrogate model uncertainty, numerical discretization error, and model discrepancy, into CEDO.
Many model discrepancies likely result from poorly characterised biological processes.
Here we discuss recent approaches for resolving model-data discrepancies and building context-specific metabolic models.
We discuss extensions to the basic CTL killing model to explain this discrepancy and propose experimental tests to distinguish between them.
