Discrepancies in PMML model output on different systems
The same PMML model can produce different outputs when it is run on different systems.
Cause: Missing or invalid input values for the model
This problem might occur when input values for the model are missing or invalid.
- For the solution, see Errors when running the PMML model.
Cause: Differences in PMML algorithms programming
This problem might also occur when the PMML algorithms are programmed differently in the Pega Platform PMML engine and other third-party systems. In some cases, third-party tools have deviated from the PMML standard, which might be the cause of discrepancies. Pega Platform adheres to the PMML standard to execute the PMML definition.
- To ensure that there is no problem with the PMML engine on your Pega Platform instance, ask a PMML developer and system architect to investigate the discrepancies that occurred.
