Macro: Apply on all examples, not only on one

Legacy User

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,

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.

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.

Best,
Elena

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
