Firstly let me offer my congratulations. I gather that you have been shortlisted for the Henry Blowfelt memorial prize for forum constipation with your magnificent nine entries on today's front page; of course there are murmurings that there are much less than nine separate topics really there, and that repeating pushes others down the heap, but I'm more liberal, nothing exceeds like excess.
I am however horrified at the agony that the attribute/feature question causes you, even the WEKA Magi Witten and Frank conspire to spread the confusion. In the index to their steamy novelette " Data Mining " I see the following entry for "Features"
features. See attributes
feature selection, 341. See also attribute selection.
As for myself, I console myself with the whimsical notion that a feature is one or more attributes, but I think that the highest authorities should be informed of this threat to our mental security. Where are the Thought Police when you need them?
