Integrating Logical and Probabilistic Reasoning for Decision Making [article]

John S. Breese, Edison Tse
2013 arXiv   pre-print
We describe a representation and a set of inference methods that combine logic programming techniques with probabilistic network representations for uncertainty (influence diagrams).  ...  Given a query, a logical proof is produced if possible; if not, an influence diagram based on the query and the knowledge of the decision domain is produced and subsequently solved.  ...  Probabilistic Inference Inference is initiated by a identifying an initial goal (the query), Go= (P t1 t2 .... tk), and an empty influence diagram, N.  ...
