Pivotal Pruning of Trade-offs in QPNs
Silja Renooij, Linda van der Gaag, Simon Parsons, Shaw Green
Qualitative probabilistic networks have been designed for probabilistic reasoning in a qualitative way. Due to their coarse level of representation detail, qualitative probabilistic networks do not provide for resolving trade-offs and typically yield ambiguous results upon inference. We present an algorithm for computing more insightful results for unresolved trade-offs. The algorithm builds upon the idea of using pivots to zoom in on the trade-offs and identifying the information that would serve to resolve them.
Keywords: qualitative probabilistic networks, trade-off resolution
