摘要:

这项工作提出了行动网络作为一个语义上有充分依据的框架推理下的行动和变化的不确定性。行动网络为概率因果网络增加了两个基本元素:可控变量和持久变量。可控变量允许将动作表示为直接设置域中特定事件的值,但要遵守前提条件。持久性变量提供了一个持久性的规范模型,根据这个模型,变量的状态和决定其值的因果机制都随着时间的推移而持续存在,除非受到动作(或其后果)的干预。行动网络还允许不同的方法来量化因果关系中的不确定性,这超出了传统的概率量化。本文介绍了最近的成果和工作进展。

英文摘要:

This work proposes action networks as a semantically well-founded framework for reasoning about actions and change under uncertainty. Action networks add two primitives to probabilistic causal networks: controllable variables and persistent variables. Controllable variables allow the representation of actions as directly setting the value of specific events in the domain, subject to preconditions. Persistent variables provide a canonical model of persistence according to which both the state of a variable and the causal mechanism dictating its value persist over time unless intervened upon by an action (or its consequences). Action networks also allow different methods for quantifying the uncertainty in causal relationships, which go beyond traditional probabilistic quantification. This paper describes both recent results and work in progress.
