ART2模型包括输入层为5个节点,用来输入5个财务指标比率,输出层3个节点,分别表示信用风险的三个级别(正常,关注,可疑),这里应用ART2模型将信用风险分为三个级别有如下几个原因:(1)将信用风险分为三个级别,比前面使用统计方法和BP模型方法将信用风险简单分成两类(违约、非违约)更容易把握风险的程度,更接近实际信用风险评估的需要,也更贴近于国际通用的五级分类标准。(2)通过ART2网络门限值参数的调整可以将信用风险分为国际通用的五级分类标准,这也正是ART2模型的优势所在,但是ART2网络是信用风险分析混合专家系统的组成部分,它的评估结果要作为输入,输入到专家系统中,以便信用风险评估专家系统进行定性及定量的综合评估,考虑到专家系统的规则的数量和知识库的规模对系统执行效率的影响,因此这里将信用风险分为三类。
