摘要:

偏序形式结构分析(POFSA)作为一种新兴的认知学习模型,在知识处理领域得到了广泛的应用。为了提高模型的可解释性和分类性能,本文提出了三向因果属性偏序结构(3 WCAPOS)方法,将POFSA从集合覆盖演化为因果覆盖。首先,因果因子(CF)的概念被提出来评估之间的因果关系的属性和决策属性的正式决策背景。然后,将CF与属性偏序结构相结合,定义了因果属性偏序结构的概念,使集合覆盖演化为因果覆盖。最后,结合三方决策的思想,形成了3 WCAPOS,使结构中节点的纯净度更清晰,层次之间的变化更明显。此外,通过六个数据集,从分类能力和结构的可解释性进行了实验。实验结果表明,3 WCAPOS的分类准确率比分类回归树提高了1%~ 9%,比属性偏序结构更具有可解释性,知识的处理更合理。

英文摘要:

As an emerging concept cognitive learning model, partial order formal structure analysis (POFSA) has been widely used in the field of knowledge processing. In this paper, we propose the method named three-way causal attribute partial order structure (3WCAPOS) to evolve the POFSA from set coverage to causal coverage in order to increase the interpretability and classification performance of the model. First, the concept of causal factor (CF) is proposed to evaluate the causal correlation between attributes and decision attributes in the formal decision context. Then, combining CF with attribute partial order structure, the concept of causal attribute partial order structure is defined and makes set coverage evolve into causal coverage. Finally, combined with the idea of three-way decision, 3WCAPOS is formed, which makes the purity of nodes in the structure clearer and the changes between levels more obviously. In addition, the experiments are carried out from the classification ability and the interpretability of the structure through the six datasets. Through these experiments, it is concluded the accuracy of 3WCAPOS is improved by 1% - 9% compared with classification and regression tree, and more interpretable and the processing of knowledge is more reasonable compared with attribute partial order structure.
