Hey,

Are there any plans to introduce a new node in the Statistics/Regression section which can take chemical fingerprints as input to generate a regression model predictor.

This seems somewhat of a missing feature in KNIME, as currently there is only the Fingerprint Bayesian Classification Model.

Simon.

Hi Simon,&nbsp;

I've logged this request in our issue tracking system. &nbsp;FYI, the naive bayes fingerprint nodes were sponsored development project. &nbsp;I'll look into the feasiblity of extending this feature set to include regression nodes as well.&nbsp;

Regards, Aaron

Many thanks Aaron. Incorporating a regression node would be extremely beneficial to all pharma colleagues in generating various predictive models.

Thanks

Simon.

Hi Simon,

The [Tree Ensemble Learner (Regression)](https://forum.knime.com/sites/default/files/inline-images/_labs_treeensemble_Tree_Ensemble_Learner_Regression_.html)/Predictor also has regression variant and accepts molecular fingerprints. The description also refers to the [classification learner](https://forum.knime.com/sites/default/files/inline-images/_labs_treeensemble_Tree_Ensemble_Learner.html), which is described here (and has other pointers to wikipedia).

Hey bernd,  
Thanks for pointing me to this, this is perfect, just what I need, and it seems to be working pretty well.  
Cheers  
Simon.
