问题描述

我有一个从 SAS Miner 生成的 PMML,我无法使用 JPMML 1.1.4 对其进行正确评估.JPMML 1.1.4 说它支持 PMML 4.2,而 PMML 说它是 PMML 4.2 版.

I have a PMML generated from SAS Miner that I can't get properly evaluated using JPMML 1.1.4. JPMML 1.1.4 says it supports PMML 4.2 and the PMML says it is PMML version 4.2.

以下函数SAS-EM-String-Normalize"中的 FMTWIDTH 是正确的 PMML 语法吗?

Is the FMTWIDTH in the below function "SAS-EM-String-Normalize" proper PMML syntax?

知道为什么我不能使用 JPMML 评估这个函数吗?

Any ideas why I can't evaluation this function using JPMML?

我的 TransformationDictionary 中的函数看起来像,

I have the function in my TransformationDictionary that looks like,

<TransformationDictionary>
    <DefineFunction name="SAS-EM-String-Normalize" optype="categorical" dataType="string">
        <ParameterField name="FMTWIDTH" optype="continuous"/>
        <ParameterField name="AnyCInput" optype="categorical"/>
        <Apply function="trimBlanks">
          <Apply function="uppercase">
            <Apply function="substring">
              <FieldRef field="AnyCInput"/>
              <Constant>1</Constant>
              <Constant>FMTWIDTH</Constant>
            </Apply>
          </Apply>
        </Apply>   
    </DefineFunction>
</TransformationDictionary>

我得到以下异常,

推荐答案

根据PMML 内置函数substring"的正式定义,它需要一个字符串参数和两个整数参数.SAS EM 生成的 PMML 代码尝试使用字符串参数、整数参数和另一个字符串参数 substring($AnyCInput, 1, "FMTWIDTH") 调用此函数.

According to the formal definition of the PMML built-in function "substring", it requires a string argument and two integer arguments. The SAS EM generated PMML code attempts to invoke this function with a string argument, an integer argument, and another string argument substring($AnyCInput, 1, "FMTWIDTH").

可以通过使用 FieldRef 元素访问FMTWIDTH"参数的值来修复此 PMML 片段:

This PMML fragment can be fixed by accessing the value of the "FMTWIDTH" parameter using the FieldRef element:

<Apply function="substring">
  <FieldRef field="AnyCInput"/>
  <Constant>1</Constant>
  <FieldRef field="FMTWIDTH"/>
</Apply>

总之,JPMML 是正确的,SAS EM 是错误的.

In conclusion, JPMML is a correct and SAS EM is wrong.
