is the order of attributes when doing a similarity comparison?
Contributor II
Hi all,
When I have two example sets that contain the same attributes but in a different order... Do similarity computations take that into account or are they relying on the fact that attributes are in the same order?
Or, does [aap=1, noot=0] compared to [noot=0, aap=1] give the Euclidian distance zero or srt(2)?
thanks,
Willem

The last time I tried this I found that the order does matter.
