选择函数推理变得实用

Inference with Choice Functions Made Practical

Ghent University(根特大学)

Arne Decadt, Jasper De Bock, Gert de Cooman

摘要:

我们研究如何以保守的方式从以前的选择中推断出新的选择。为了做出这样的推论,我们使用选择函数理论:保守决策的统一数学框架,允许人们直接将公理强加于所代表的决策。我们在这里采用De Bock和De Cooman(2019)的一致性公理。我们展示了如何自然地将任何给定的选择评估扩展到这样一个连贯的选择函数,只要有可能,并使用这种自然扩展来做出新的选择。我们提出了一个实用的算法来计算这个自然的扩展,并提供了几种方法,可以用来提高其可扩展性。

英文摘要:

We study how to infer new choices from previous choices in a conservative manner. To make such inferences, we use the theory of choice functions: a unifying mathematical framework for conservative decision making that allows one to impose axioms directly on the represented decisions. We here adopt the coherence axioms of De Bock and De Cooman (2019). We show how to naturally extend any given choice assessment to such a coherent choice function, whenever possible, and use this natural extension to make new choices. We present a practical algorithm to compute this natural extension and provide several methods that can be used to improve its scalability.
