Loop K-means - how to write csv chosing the # of K
Learner I
Hi there,
I'm running a process with loop k-means (K=2 - k=13), manually comparing the DB of each k I like the results of K=3.
Now I want to write an csv file with a new attribute, the cluster (0, 1, 2) but when I add the operator to this process it writes the file based on k=13.
attached is the data set and bellow the process' xml.
Thanks in advance!

I have tried to add that macro on the file name but it resulted in:
Then I tried to use the operator "set macro", but when I ran it the csv file contained 13 clusters and not the total 3 clusters I wanted (that is, the same result as without the macro)
Maybe I did something wrong... I'm new to all this!
can you help?
thanks!
Sure, I have added XML of a process that you can check out, the processes saves 5 files one for each row using the macro approach. You can update the path based on your directory for testing. In the essence, you will have to incorporate the similar process in your clustering piece, where in you can use extract macro to figure out the current k and then save the file with k-value embedded in the file name.
Let me know if this works for you.
