Predictive Model Markup Language (PMML) is an XML-based standard specified by the Data Mining Group (
http://www.dmg.org). Applications that are PMML-compliant can deploy PMML-compliant models that were created by any vendor. Oracle Data Mining supports the core features of PMML 3.1 for regression models.
You can import regression models represented in Predictive Model Markup Language (PMML). The models must be of type
RegressionModel, either linear regression or binary logistic regression.
