Dear all,
I propose an easy challenge in appearance (in appearance only)... After many tests, I must admit that
I'm totally stuck.
My process produces an example set with some attributes (the number of generated attributes is variable according to the set-up of the user) :
For a given attribute, I want to filter the example values based on the attribute name :
- if the example value contains the attribute name, then the example is conserved.
- if the example value does not contain the attribute name, then the example is removed.
To perform this task, I try to used a
Filter Examples operator inside a
Loop Attributes subprocess with the following set-up :
-
condition class = expression and
parameter expression =
= >
this solution produces an empty example set ! -
condition class = custom_filters and
filters = 
= >
this solution raises an error ("Instantiation error") :
So I'm searching a 100 % native RapidMiner process (no Python / R scripts) to filter example values based on the
attribute name. Is it possible ?
My data (.pdf file) is in attached file.
