How to "loop" over a filter?
Hey everybody,
I have a dataset containing the hours of a day of the whole year. What I want to do is to filter each day. Obviously doing that manually would be very hard, as I had to do that 365 times. Is there a way to somehow loop this thing?
Thanks

Thanks for your reply,
that sounds pretty good. But could you specify? I downloaded the operator toolbox, but as soon as I put the Group into Collection operator into the Loop Collection operator the Error Message "Expected IOObjectCollection but received Examples set" occurs. Since I would call myself a newbie I would be grateful if you could provide me how to do so :-).

And besides that is it possible to group by 2 attributes?

Okay, I solved this by putting another Group into Collection operator into the loop collection?! Now the problem occured that I can't join a collection with another dataset?
Altair EmployeeHi,
i currently cannot run you proces, but i think you need to use an append before the join to get an example set again.
Edit: For the two attributes. Thats on our list to add. The Toolbox extension is a community like extension, even tough it is a rapidminer-interal community . So far you need to go for Generate Attribute and Concat to do two attributes.
Loop Values with Filter Example is by the way also a viable option, but slightly slower in execution time.

Oh, okay. That's maybe because I have so many dataset etc.
But if I append now I have the same result as before. What I whant to do is to join every collection in this case e.g. 365 with another example set (which contains e.g. the name of the days of the week). So to append wouldn't be an option or?
Altair EmployeeI think you need to get the data set into your loop collection using remember recall. See attached process
With 1-2 more operators we could use a usual loop, with select operator. The standard loop has an additional input and is working in parallel. Quite some options to go there .
Best,
Martin

I think we are near the finish line. Thank you for your process, that looks like it can work. But there is one error message occuring in the recall "no object with name data was found" despite we set it "data" in remember operator.
Altair EmployeeCould you check if the remember operator is executed before the recall?
Best,
Martin
Thanks for your fast response.
According to RapidMiner it is definitely executed before the recall.
Altair EmployeeGot it, Could you remove the remove from store option in recall. Otherwise it's not available in iteration 2. Sorry for this.
~Martin
If I "remove from store" to negative it works :-). Is that plausible?
Okay, I did it parallel. Thank you very much for this long discussion and helpful answers! Process works fine now :smileyhappy:
Best regards
Philipp
Altair EmployeeYes,
usually the objects are deleted once you recall them. This is to safe memory. In your special case you do not want to have it deleted. if you deactivate this option it's deleted once your process finishes.
~Martin
Hello again,
I have a question concerning the metadata, because if I want to apply replace missing values (series) on each IOObject I can't pick them in the dropdown of the operator. :smileyfrustrated:
Altair EmployeeHi,
you an simply type in the attributes by hand. It works anyway.
I think we need to investigate our meta data propagation there. But maybe it's just fine to take the meta data from Last execution (under Process).
~Martin
Thank you that also worked! :-)
Now that I wanted to do two collections (2 attributes) I created another collection of the collection. The Input of the join operator then says that it's the wrong input type.
Altair EmployeeHi,
do you want to group by two attributes? If so, then first built an indicator variable like concat(att1,att2) and then do one grouping.
~Martin
Okay that worked. Thank you! I think it's the routine, which hopefully lets me find this kind of solutions, too.
The whole process is finished now. It works fine, but is would there be a way to create or rather get back the meta data? It took me some typing to manually write all attribute names in a couple of different operators.
Altair EmployeeHi,
usually Process->Synchronize Data with Real Data should do the job.
Propagating meta data from recalls in complex loops is kind of difficult..
Best,
Martin
