@HY_Z H2O.ai Automl would [support stacked models](https://docs.h2o.ai/h2o/latest-stable/h2o-docs/data-science/stacked-ensembles.html?highlight=stacked). You can use the [KNIME node](https://kni.me/n/0gd1E7-Fne7-HB5p): ![image](https://forum-cdn.knime.com/uploads/default/original/3X/8/2/82928d6796e05e5b07a0417816889014225075bc.jpeg) > **[H2O AutoML for Regression – knime](https://hub.knime.com/knime/spaces/Examples/04_Analytics/15_H2O_Machine_Learning/11_H2O_AutoML_Regression_Model~zDt85GR4CDRvyrtf/current-state)** > > This example shows how to build a regression model with H2O AutoML, predict new data and score the regression metrics for model evaluation. 1.

It has wrappers for R and Python but also could be used from KNIME. The results will be written to a folder and the models will be stored in MOJO format to be used in KNIME (as well as on a Big Data cluster via Sparkling Water). One major parameter to set is the running time the model has to test various models and do some hyperparam… --- _[View the full topic](https://forum.knime.com/t/how-to-build-a-stacking-regressor-in-knime/46674)._
