Abstract:
偏好处理是人工智能中的一个重要研究内容。cp-nets(conditionalpreferencenetworks,条件偏好网)是一个带标记的有向图,它编码相关变量之间的偏好关系。作为一种简单直观的图形偏好表示工具,却很少有工作对cp-nets的结构进行研究。研究cp-nets的结构,提出了基于g方检验对cp-nets进行结构学习的算法,并给出算法的时间复杂度为o(n?2n).作为一种对数似然比检验方法,g方检验特别适合于判断变量之间的因果关系。由于cp-nets的核心概念是条件偏好无关,因此利用g方检验可有效地实现cp-nets的结构学习。通过构造g方检验的统计量,在给定的成对比较样本集中,执行零假设检验,从而依次求出每个顶点的父亲集,进而得到cp-nets的结构。最后,通过随机生成的模拟数据,验证了所提出算法的有效性。与相关cp-nets的学习算法对比,本文提出的方法具有被动的,离线的,和基于统计学习的特征。
