WebbWe consider the problem of reasoning with uncertain evidence in Bayesian networks (BN). There are two main cases: the first one, known as virtual evidence, is evidence with uncertainty, the second, called soft evidence, is evidence of uncertainty. The initial inference algorithms in BNs are designed to deal with one or several hard evidence or … Webb25 maj 2024 · drbenvincent May 25, 2024, 11:27am 1.
