Loop 2 attributes at once

edited June 2019 in Help
Hello,

I've got a question again and you seem to be amazing at answering them. 

I'm trying to use a loop where I want to filter for 2 things at once inside the loop. I have a dataset with multiple attributes where I have a series of steps that need to be executed for two attributes each with their own series of steps. These need to be executed twice. 

First iteration Loop attribute 1&2, second iteration loop attribute 3&4. Is this possible or do I need to use two separate loops for this? 

I've tried using a macro in the loop function, I made two separate macros with the same name as value 1 and the other 2, but this does not work. 
I also tried using two separate loops but the output is not what I want it to be. Now I need to link one attribute from one loop to one attribute of the other loop. 

If anybody knows how one of these can be accomplished I would really appreciate it.

Thanks
-Prentice

    If your columns are named in a good way, like I am showing here. You can definitely run with a single loop.

    Honestly I cheated here to only keep one single loop by renaming the columns: every column falling into either bucket .*Failure, .*Inspection makes it easier to search for the columns and merge.

    Basically, you will need to have loop inside loop. But you can concatenate the attributes 1,2, 3, 4 and iterate thru all possible concatenated values with only one loop. If you could share sample data, we can help you build a backbone prototype.

    This is an example of what my process looks like. As you can see I have the attributes animal and animal type that have two different tasks. But I also have vehicle and vehicle type which have the same tasks as animal and animal types. To make my process more efficient I would like to use a loop for these.

    Thank you for the sample process that creates the data, @Prentice!
    I saw two independent data sets, one for TF-IDF of vehicles , 9 rows x 16 columns

    another TF-IDF for animals , 10 rows x 18 columns

    We can loop values in animal type or loop values in vehicle type. The two data sets have different columns names, dimensions, and no overlapped values, so we can not loop them at once by any dimension. But you can append the text table and get tf-idf on the merged data set at once and then you will have a full table with everything.

    Maybe you have some better example set to elaborate your ideas? 

    Thanks!

    Ok, I got another example. This one is as close as it can get to what I have/want. To reiterate my question: Is there anyway this can be looped in one loop or do I need to use 2? 

    And I do want the output to be the same, as two independent datasets. I'm just trying to be as efficient as possible

    (Also, how can I properly put the XML in here?)

    Hi Prentice,

    I still don't understand what you are trying to do from a machine learning perspective. I don't see any loop in your process either.

    If there are 2 different real world processes, I don't see any problem in having 2 separate datasets. Regarding the efficiency, it is the same: more loops on thinner datasets result on the same processing time.

    Regarding the XML, you can use the format icon in the text editor, it is the 6th icon from the left. The spoiler format is the best I think.

    Regards,
    Sebastian

    To insert codes for process, you can use the button and add a paragraph of Code

    If you have very long scripts, you can insert the Code inside Spoiler :)

    Ah ok thanks, I just thought that loop would decrease the computation time, but apparently it does not. 
  • PrenticePrentice Member Posts: 66 Maven
    Yes! This is exactly what I'm looking for!
    However, there's only one flaw here and that is that I cannot change the attribute name from the source. This means I can use the rename operator to change these first. However, I don't know how to change them back. But, is it even necessary? Because I'm using this for classification and it doesn't show the attribute name as output right? 

  • yyhuangyyhuang Administrator, Employee-RapidMiner, RapidMiner Certified Analyst, RapidMiner Certified Expert, Member Posts: 364 RM Data Scientist
    You can use a separate data table to list and (meta-data) manage the attributes from the source, in the list for metadata you can define which two should be joined/merged together inside the loop. So renaming is not a necessary.

    Ok, thanks for all your help for this case!
