Can HANA KNN Nearest Neighbor be Used from Predictive Factory?

I found in documentation that HANA KNN Nearest Neighborhood is not supported for Expert Analytics standalone. We have a good model built on this algorithm and would like to use it on a regular basis as well as leverage the scheduled retraining capabilities in Predictive Factory. Has anyone brought a model, or model chain, into Predictive Factory using HANA KNN Nearest Neighbor? Would this need to be done by consuming a HANA stored procedure or imported from a model chain?

If a model chain, anyone have a good set of steps on how to export from PA Expert to a chain, or does it require running in standalone mode to do that, and this would be unsupported in that fashion?

Or is it completely unsupported in this scenario and I meed to look to using the R flavor of the NN algorithm instead?

Hello Chris, if Expert Analytics does not support HANA KNN you would not be able to import it to Factory. Have you considered using the Automated Clustering algorithm? The good thing about it is that you can use supervised clustering. Thanks and kind regards, Antoine

Thank you for the response. I'll run the supervised clustering idea by our Data Scientist working on the project.
