摘要翻译:
本文研究了一种将数字信息和定性信息相结合的半定性概率网络。我们首先证明了SQPN的精确推理是NPPP完全的。然后,我们证明了SQPN中存在的定性关系(加上概率逻辑和不精确评估)可以通过多线性规划有效地处理。然后我们讨论学习:我们考虑了一种最大似然方法,它在给定SQPN和经验数据的情况下生成点估计,我们描述了一种贝叶斯思想的方法,它使用不精确的Dirichlet模型生成集值估计。

英文摘要:
This paper explores semi-qualitative probabilistic networks (SQPNs) that combine numeric and qualitative information. We first show that exact inferences with SQPNs are NPPP-Complete. We then show that existing qualitative relations in SQPNs (plus probabilistic logic and imprecise assessments) can be dealt effectively through multilinear programming. We then discuss learning: we consider a maximum likelihood method that generates point estimates given a SQPN and empirical data, and we describe a Bayesian-minded method that employs the Imprecise Dirichlet Model to generate set-valued estimates.
