修正不完整的态度

贝叶斯模型通常假设代理人是理性的、逻辑上无所不知的、固执己见的。然而，最后一种情况几乎没有描述性或规范性的吸引力，并且限制了我们描述代理人如何下定决心（而不是改变他们）或如何暂停或撤回他们的意见的能力。为了解决这些限制，本文通过一组（允许的）概率和可取性函数来表示非固执代理的态度状态。这种心态可以改变的几种基本方式，然后被描述并与那些在态度修正的AGM风格模型中发现的方式进行比较。最后，这些模型被用来描述agent在商议时如何做决定。
Bayesian models typically assume that agents are rational, logically omniscient and opinionated. The last of these has little descriptive or normative appeal, however, and limits our ability to describe how agents make up their minds (as opposed to changing them) or how they can suspend or withdraw their opinions. To address these limitations this paper represents the attitudinal states of non-opinionated agents by sets of (permissible) probability and desirability functions. Several basic ways in which such states of mind can be changed are then characterised and compared with those found in AGM style models of attitude revision. Finally these models are employed to describe how agents make up their mind when deliberating.
