Predictive Models everywhere!PMML in KNIMEAlexander Fillbrunn
PMML in KNIME• Standard for passing models and
preprocessing information between nodes• Can be im‐ and exported from and to various
other tools• Built in a modular fashion parallel to the data
flow
PMML
Lightning‐Fast Prediction with Compiled Models• Translate PMML into Java code• Up to 4 times faster model execution• Supports all KNIME‐generated PMML models
Ensemble Models• Multiple models in one package• Aggregate results of contained models• Better predictions than with single model• Various nodes in KNIME to buildand modify such models
