关于概率的缺省推理逻辑

A Logic for Default Reasoning About Probabilities

Max-Planck-Institut fur Informatik(马克斯·普朗克信息学研究所)

Manfred Jaeger

摘要:

定义了一种逻辑,它允许表达关于统计概率和关于特定命题的置信度的信息。通过在一个共同的概率空间中解释两种类型的概率,给出的语义非常适合于模拟统计信息对主观信念形成的影响。交叉熵最小化是这些语义中的一个关键元素,它的使用是合理的,表明所产生的逻辑表现出一些非常合理的属性。

英文摘要:

A logic is defined that allows to express information about statistical probabilities and about degrees of belief in specific propositions. By interpreting the two types of probabilities in one common probability space, the semantics given are well suited to model the influence of statistical information on the formation of subjective beliefs. Cross entropy minimization is a key element in these semantics, the use of which is justified by showing that the resulting logic exhibits some very reasonable properties.
