is the order of attributes when doing a similarity comparison?

wasperen

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

Hello Willem

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