[SOLVED] Loop attributes

Hi,

I am working with a dataset containing 60 attributes, each having 700 examples (and no missing values).
Attribute types are either real oder integer.
10 attributes (allways the same ones) are "normal", the remaining 50 are potential "label" attributes.

What I want to do is pick 1 of the remaining 50 attributes, set it as label, run the now 11 attributes through a Linear Regression and store the result.
My problem is that I dont want to do this 50 times manually (select a new label attribute, rename the store operator and run the process).

So my question is: Is it possible to automatically loop through the 50 potential labels and store each result file in the same folder (ideally having the name of the label) with the help of a loop operator (so i will only have to start the process once and get 50 result files out of that).

Ps.: I have allready seen the loop operators in RM, but did not have time to test things out yet.

Yes, that's possible with the Loop Attributes operator.

Best,

Hey, thanks so far!
But I can't seem do get it working.
Could anyone explain a little more detailed (or give me a tutorial) on how the loop operators work?

Edit: to be more precise: I selected a subset of attributes in the Loop Attributes operator and now want it to set the one it has selected right in this loop as label

Jagsus

Nobody? I am trying for 3 hours now and I just have no clue how I can get this working.

Hi there,

Searching this forum for 'loop attributes' may help, but here's a link that may be useful anyway.

http://rapid-i.com/rapidforum/index.php/topic,2351.msg9346.html#msg9346

Hope so.

Jagsus

Thanks, I'll check that during the day and give a response when I'm done!

Sadly, this did not help me. (Maybe because my Rapidminer Skill are absolutely on a beginner level)

What I managed to build is the following (still not working)

Idea behind this:
First i take my dataset and select all possible lable attributes, give them into the loop and set one as lable.
At the same time I load the dataset a second time within the loop, select all the "all time variables" and join them to a number of new datasets equal to the possible lable attributes, each set containig one different lable and the same "all timers". But this process just runs until I force-close the program.

I'm sorry for all the trouble my lack of skills might cost and I really appreciate your help!

Ps.: I did a forum search for "loop attributes" but didn't find something helpfull (at leat from my point of view)

Jagsus

Hey guys,

I have tried several times over the week but I still allways condemned what I had because nothing worked.
It may sound a little desperate at this point, but as I start to feel incredibly stupid each time I open Rapidminer because the result is probably pretty simple and I just can't figure it out, so: Could someone please pass me some XML-Code that might work on the problem described in post 1?
That would be really awesome!

Ps.: And yes, I have searched the forums and google and work with the Loop Attributes and Work on Subset operators

As an aside I would you urge to read the documentation, and work through the examples, rather than Google for an answer.

Jagsus

Thanks! With my current knowledge i would never have gotten so far.

Just one (hopefully) last thing:
Could you explain what happens inside the "Work on subset" operator? The rest is clear to me.

Hi there,

You can see that the process just thins down the attribute set to 1 label and the same 5 attributes, and logs that; so just before that log operator you can do your learning, or optimisation, or whatever. If you put a break before the log operator you can see the example set that would be available, like this.
