增强QPN以解决权衡问题

Enhancing QPNs for Trade-off Resolution

Utrecht University(乌得勒支大学)

Silja Renooij, Linda C. van der Gaag

摘要:

定性概率网络是贝叶斯信念网络的定性抽象。这些定性网络的主要缺点之一是其粗糙的细节水平,这可能导致在推理过程中无法解决的权衡。我们提出了一个增强的形式主义定性网络的细节层次更精细。增强型定性概率网络与常规定性网络的不同之处在于,它区分了强影响和弱影响。增强的定性概率网络本质上是纯定性的,就像常规的定性网络一样,但允许在推理过程中有效地解决权衡。

英文摘要:

Qualitative probabilistic networks have been introduced as qualitative abstractions of Bayesian belief networks. One of the major drawbacks of these qualitative networks is their coarse level of detail, which may lead to unresolved trade-offs during inference. We present an enhanced formalism for qualitative networks with a finer level of detail. An enhanced qualitative probabilistic network differs from a regular qualitative network in that it distinguishes between strong and weak influences. Enhanced qualitative probabilistic networks are purely qualitative in nature, as regular qualitative networks are, yet allow for efficiently resolving trade-offs during inference.
