WebEvidence theory. Like a probability measure in probability theory, a basic probability assignment lies in the foundations of evidence theory, also known as the Dempster-Shafer theory (Dempster, 1967 ), ( Shafer, 1976 ). A basic probability assignment is a mapping m from the set of all subsets of a universal finite nonempty set X to the interval ...

A Dempster-Shafer belief structure … WebMay 16, 2024 · To be specific, a mass function in the generalized Dempster–Shafer evidence theory is modeled by a complex number, called as a complex basic belief assignment, which has more powerful ability to express uncertain information. Based on that, a generalized Dempster’s combination rule is exploited. In contrast to the classical …
