"Brute Force Feature Selection"

I am using the Brute Force Feature Selection operator to go through all different combinations of my attributes (total: 10). Is there a way to create a file containing the attributes that are used and the corresponding performance in each row so that I can see exactly which combination of attributes gives what performance? E.g.

Features Performance
A,B,C 0.8
B,D,G 0.6
C,D,E,F,G 0.7
B,E,H 0.9
...

I have tried using ProcessLog operator but the feature_name value in the Brute Force Feature Selection operator don't seem to work. It just output the value '?'.

    Hi pengie!

    I think it should work with the log operator. Can you please post your process setup. This way we can exactly see what you are doing and helpmore appropriate.

    Hi there,

    Chero's right, you'll need to iterate over the attributes to build a macro, and then log that, like this...





























    <操作符名称= " Macro2Log " class = "Macro2Log">
