Types of reasoning permitted in BBN's

When using BBNs we are interested in making predictions about uncertain quantities conditioned upon some evidence. Mathematically the meaning of the | in p(A | B) is straightforward but when modelling the real world we must be careful to ensure that conditioning is employed only to model sensible statements about the world. There are a number of types of reasoning that can be considered as valid conditional propositions in a BBN and the purpose of this section is to provide an overview of what the permitted reasoning types are and outline their differences. The different modes of reasoning described are:

Finally we explain how these different types of reasoning are handled by the SERENE idioms.
