The Role of Uncertainty in Models of Epistemic Curiosity
Современная зарубежная психология, 2022 The psychological research strategies of studying epistemic curiosity traditionally consider four factors of motivation to search for new information: the degree of familiarity with the subject, the expected value of information, the cultural ...

Quantifying Epistemic Uncertainty in Deep Learning
CoRR, 2021 Uncertainty quantification is at the core of the reliability and robustness of machine learning. In this paper, we provide a theoretical framework to dissect the uncertainty, especially the \textit{epistemic} component, in deep learning into \textit{procedural variability} (from the training procedure) and \textit{data variability} (from the training ...

Combinatorial Reliability Evaluation of Multi-State System with Epistemic Uncertainty [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2022 Multi-state systems (MSSs) are common in real-word applications, in which a system and/or its components exhibit multiple stochastically-dependent states or performance levels.

DEUP: Direct Epistemic Uncertainty Prediction
Trans. Mach. Learn. Res., 2021 Epistemic Uncertainty is a measure of the lack of knowledge of a learner which diminishes with more evidence. While existing work focuses on using the variance of the Bayesian posterior due to parameter uncertainty as a measure of epistemic uncertainty, we argue that this does not capture the part of lack of knowledge induced by model misspecification.

The multi-assumption architecture and testbed (MAAT v1.0): R code for generating ensembles with dynamic model structure and analysis of epistemic uncertainty from multiple sources [PDF]
Geoscientific Model Development, 2018 Computer models are ubiquitous tools used to represent systems across many scientific and engineering domains. For any given system, many computer models exist, each built on different assumptions and demonstrating variability in the ways in which ...

Acquisition of epistemic marking in Estonian and Russian
Eesti Rakenduslingvistika Ühingu Aastaraamat, 2016 The article compares the acquisition of epistemic modality in typologically different languages, Estonian and Russian. The longitudinal data of 4 children was used to analyse the first emergence and the further development of lexical markers expressing ...

Applied Sciences, 2021 Aleatoric and epistemic uncertainties can be represented probabilistically in mechanical systems. However, the distribution parameters of epistemic uncertainties are also uncertain due to sparsely available or inaccurate uncertainty information ...

Atom Indonesia, 2015 Components of nuclear power plants do not always have historical failure data to probabilistically evaluate their reliability characteristics. To overcome this drawback, an alternative approach has been proposed by involving experts to qualitatively ...

Seismic Risk of Infrastructure Systems with Treatment of and Sensitivity to Epistemic Uncertainty
Infrastructures, 2020 Modern society’s very existence is tied to the proper and reliable functioning of its Critical Infrastructure (CI) systems. In the seismic risk assessment of an infrastructure, taking into account all the relevant uncertainties affecting the problem is ...

Embracing epistemic uncertainty: a risk evaluation method for pollutants in stormwater
Water Science and TechnologyIn this study, we show that pollutants of emerging concern are, by nature, prone to the emergence of epistemic uncertainty. We also show that the current uncertainty quantification methods used for pollutant modelling rely almost exclusively on parameter
