TAXONOMIC HIERARCHIES, CONTINUOUS VARIABLES, AND UNCERTAIN PROBABILITIES
Publisher Summary
This chapter presents propagation rules that, like those developed for causal networks, allow evidence to be pooled through local computations, under local control. The chapter presents an encoding scheme that stores and manipulates the belief distributions and the support messages rather than storing them explicitly as in the case of discrete variables. The encoding scheme is based on three assumptions: (1) all interactions between variables are linear, (2) the sources of uncertainty are normally distributed and are uncorrelated, and (3) the causal network is singly connected. Even though the mathematical derivations rely on these three ...
