I came into a problem today that i didn't think about it before.
I have sets of features:
Some sets have only 1 feature. other 5 features.
Example: set1 = [f1], set2 = [f1,f2,f3,f4], set3 = [f1.....f20] etc...
as u can see Set2 will have more weight than set 1 in a classification and set3 will have more weights than all of them.
So My question is how can make set 1 equal in weight like set2. Is there way to give a weight to set1? or normalization?
It's a very hard question. I almost completed the tests. While i thought of that problem.
bad luck i guess.
anyway Thank you for your help!
