条件、概率和逻辑的布尔代数

Boolean algebras of conditionals, probability and logic

Tommaso Flaminio, Lluis Godo, Hykel Hosni

摘要:

本文提出了一个调查的结构条件事件和概率测度,自然出现在这种情况下。特别是,我们介绍了一种结构,它定义了一个(有限){ \em布尔代数的条件}从任何(有限)布尔代数的事件。通过这样做,我们区分条件事件的属性取决于概率和那些内在的逻辑代数结构的条件。我们的主要结果提供了一种方法,把标准的两个地方的条件概率作为一个地方的概率函数的条件事件。我们还考虑了我们的布尔代数的条件链接到非单调推理的优先后果关系的逻辑对应。本文的整体框架提供了一个新的视角,丰富的逻辑和概率之间的相互作用,在条件知识的表示。

英文摘要:

This paper presents an investigation on the structure of conditional events and on the probability measures which arise naturally in this context. In particular we introduce a construction which defines a (finite) {\em Boolean algebra of conditionals} from any (finite) Boolean algebra of events. By doing so we distinguish the properties of conditional events which depend on probability and those which are intrinsic to the logico-algebraic structure of conditionals. Our main result provides a way to regard standard two-place conditional probabilities as one-place probability functions on conditional events. We also consider a logical counterpart of our Boolean algebras of conditionals with links to preferential consequence relations for non-monotonic reasoning. The overall framework of this paper provides a novel perspective on the rich interplay between logic and probability in the representation of conditional knowledge.
