If your predictive models do not work as expected, use the following tips to troubleshoot and solve the most common issues that you may experience when working with predictive models.
- A PMML file cannot be used to create a predictive model
The PMML file that you uploaded contains unsupported features in its model definition.
- A PMML model contains undefined functions
The PMML engine of Pega Platform does not recognize some of the functions that are part of the PMML model that you uploaded.
- Discrepancies in PMML model output on different systems
The same PMML model can produce different outputs when it is run on different systems.
- Errors when running the PMML model
When you run a strategy that references a Predictive Model rule instance, an error that is related to the PMML file that is uploaded in the rule instance might occur.
