Hi all!

I've been playing a bit with clustering and came to the situation where I would like to be able to use the cluster centers of a cluster model as example set (I would basically like to feed the clusters centers to a previously built decision tree).
Unfortunately I couldn't find any operator that allows me to do so. Is there an automatic way to convert cluster centers to an example set?

Thanks a lot!

Hi Damon,
unfortunately there is no such operator until now. But I've added it on my todo list.

It should already be possible:

1) cluster the data
2) divide the data into groups according to the cluster name, e.g. with the ValueIterator + ExampleFilter
3) calculate the mean values for all features and store them by using the process log
4) build an example set from the process log table

Just a tip: be creative! I often think "oh, I am missing an operator here" but then after a small period of trying I always managed to get things done by using a more or less complex combination of the standard operators.

Best regards,
Jorg
