How do I use the PMML 3.2 Converter?

Simple, see our youTube video tutorial on how to use the PMML Converter.



[High Res Video: Tutorial - PMML Converter]

Just "Browse" for your PMML file; once you find it, click on "Convert". If the model is converted successfully, it will be available for download. Just click on the link provided (see image below) and save the file locally.



You can then use your new PMML file in ADAPA. However, it is not necessary for you to convert your file before uploading into ADAPA since it converts PMML files automatically.

Note that the converter expects valid PMML files. Auto-generated PMML code may sometimes contain elements that are not valid PMML. In that case, the converter will display a message stating that your file does not conform to the PMML specification. You will be able to take a look at the identified problems by clicking on the "details" hyperlink. Any errors encountered will have specific comments generated by the converter. On the very top of the file, there is also a summary comment stating how many total problems were encountered during conversion. You can use this information as feedback to obtain a valid PMML file before attempting conversion again.

For known issues with PMML files from a variety of sources/vendors, the PMML Converter will automatically correct the PMML file before converting it. In this case, the converter can also be used to validate and correct the current version of PMML files.

The PMML Converter actually encompasses three key functions: 1) Validation, 2) Correction, and 3) Conversion of PMML files to the current version. Support for version 4.0 is coming soon!

For supported PMML elements as well as known issues with auto-generated PMML code, check our other blogs under the "PMML Converter" label.
