WebMar 1, 2024 · Based on the process, we propose the fractal-baed belief entropy to measure the BPA’s total uncertainty. After 10 required evaluations, we prove that FB entropy can reasonably measure the uncertainty of BPA. In addition, we prove its superiority from 3 aspects: combination rule, non-specificity and physical model. Based on.
The theory of belief functions, also referred to as evidence theory or Dempster–Shafer theory (DST), is a general framework for reasoning with uncertainty, with understood connections to other frameworks such as probability, possibility and imprecise probability theories. First introduced by Arthur P. Dempster in the context of statistical inference, the theory was later developed by Glenn …
