Model Output PMML

[cfkstat]

Is it technically feasible to convert the model's end results into SQL scripts or PMML language? This would support model deployment in multiple environments and enhance comprehension of the predictive calculation logic.

Thank you for your question.

Khiops does not provide an export of models to SQL or PMML. The main reason is that a full Khiops model cannot be faithfully represented in these formats.

Khiops relies on a rich dictionary layer and native multi-table modeling (keys, aggregations, derived variables, discretizations, value groups, special-value handling). Standard PMML cannot express many of these operations, and generating equivalent SQL would lead to extremely complex, environment-dependent code that would be difficult to validate and maintain.

For these reasons, the project focuses on end-to-end deployment using dictionaries, through the Khiops engine and the Khiops Native Interface, which guarantee consistent and reliable scoring across environments.
