Definition 1.1. Uncertainty quantification is the science of quantitative characterization and reduction of uncertainties in both computational and real-world applications. It tries to determine how likely certain outcomes are if some aspects of the system are not exactly known. *Asch, M., Bocquet, M., & Nodet, M. (2016).
