What is epistemic uncertainty

The elasticity problems deal with stress or deformation of soil without failure.If your knowledge inputs are wrong, then all the conclusions from the models are likely to be wrong or useless (or both).Data uncertainty, also called aleatoric uncertainty, comes from mislabelled examples, noisy data, overlapping classes, etc.The epistemic uncertainty is characterized by alternative models.It relates to knowledge and whether or not the things you know are true.Epistemic uncertainty is also known as systematic uncertainty, and is due to things one could in principle know but does not in practice.

There was some discussion in comments recently about the distinction between aleatoric uncertainty (physical probabilities such as coin flips) and epistemic uncertainty (representing ignorance rather than an active probability model).This may be because a measurement is not accurate, because the model neglects certain effects, or because particular data have been deliberately hidden.3.3 and appendix a.2) of the agent or decision maker, and hence to the epistemic state of the agent instead of any underlying random phenomenon.For continuous random variabiles, the epstemicIn other words, it refers to the ignorance (cf.Epistemic uncertainty represents a lack of knowledge about the appropriate value to use for a quantity;

The type of bn determines the treatment of parameter uncertainty:
