概率选言逻辑程序设计

Probabilistic Disjunctive Logic Programming

Liem Ngo

摘要:

在本文中,我们提出了一个框架相结合的析取逻辑编程和普尔的概率角溯因。我们使用假设的概念来指定概率结构。我们考虑概率信息不可用的情况。我们不使用概率区间,而是允许指定析取的概率。由于最小模型被用作选言逻辑程序设计中的特征模型,我们应用最小模型集上的无差异原理来推导违约概率值。我们定义了公式的解释和部分解释的概念,并用它们来确定程序诱导的违约概率分布。提出了一种计算目标违约概率的算法。

英文摘要:

In this paper we propose a framework for combining Disjunctive Logic Programming and Poole's Probabilistic Horn Abduction. We use the concept of hypothesis to specify the probability structure. We consider the case in which probabilistic information is not available. Instead of using probability intervals, we allow for the specification of the probabilities of disjunctions. Because minimal models are used as characteristic models in disjunctive logic programming, we apply the principle of indifference on the set of minimal models to derive default probability values. We define the concepts of explanation and partial explanation of a formula, and use them to determine the default probability distribution(s) induced by a program. An algorithm for calculating the default probability of a goal is presented.
