Macro: Apply on all examples, not only on one

Macro: Apply on all examples, not only on one

Hello guys,

I am jsut getting familiar with macros. I am using the following workflow that I have taken from myexperiment. My problem is that it works for one single value and for all. The idea here is the following: I have a similarity matrix: id1,id2, similar. I want tofind the top 10 most similar items to a certain item(=id1). The following process works if i set the id in the xml. How can I make this work for all the id?

Thank you in advance.

Best,
Elena

P.S.: Is there a more concrete manual of macros in RM? I haven't found anything,

Re: Macro: Apply on all examples, not only on one

Hi,

you can probably use Loop Examples around your current process. Set the loop_attribute to "FIRST_ID" and iteration_macro to "id" and your process should give recommendations for all ids.

[SOLVED]Macro: Apply on all examples, not only on one

Hi Marius,

thanks for the reply. I figured this out afterall. I jst changed the whole thing.
It took me some time to figrue out that the macro input value is in the xml though. Smiley Wink

Re: Macro: Apply on all examples, not only on one

Hi Elena,

next time you can directly use the XML: in RapidMiner, go to the View menu -> Show View and make sure that the XML view is visible. There you can simply paste my XML code, and the process will be visible in RapidMiner.

Best regards,
Marius
