Segmented modeling

Hi everyone,

I'm a new user of Knime and I would like to use it to test segmented modeling.

By segmented modeling, I mean do the two following steps:

1 - segment the data in some way (random, clustering,...) thus adding a 'segment' column to the table and learn a scoring model per segment.

2 - for test data, given that you know how to add the correct 'segment' column to test data, apply the apply the model corresponding to the segment to score data and output a unique output table with a score per piece of data.

I try to work out how do loops work in knime but it's not clear for me. Any help appreciated !


Thanks !
