WebMar 1, 2009 · Uncertainties are characterized as epistemic, if the modeler sees a possibility to reduce them by gathering more data or by refining models. Uncertainties are categorized as aleatory if the modeler does not foresee the possibility of reducing them. WebMay 1, 2024 · The first type of uncertainty is often termed aleatory (or objective) and the second type epistemic (or subjective). Intuitively, probability seems a natural way of representing aleatory uncertainty (the chance of heads is 50 percent), but it may seem an abuse to apply it to epistemic uncertainty (distance appears to leave no room for …
