Further Researches and Application of Composition Process in Qualitative Bayesian
Chunsheng Cui · Science Technology and Engineering · 2009
Based on the sign-propagation algorithm of qualitative Bayesian networks,an improved composition algorithm is proposed according to actual situation.Two different logic relations of cause-node,logic-or and logic-and,are distinguished.Logic-or relation should use ⊕-operator in the composition process while logic-and should use ■perator.An example is given to validate the algorithm.
