Hi all,
I have two sets of vectors, one made of 3-dim vectors and the other one of 4-
dims vectors.
I want to find for each of my 3D vectors (let's call them the input vector),
which one, among my 4D vectors (let's call them my models), has the 3 first
coordinates that are the closest of my input vector, so that i can assign to
my input vector the 4th dimension taken from the models.
I am currently maximizing the cosine of two vectors, but I was wondering if
scipy had some more clever routines, that could for instance take into account
measurement errors for my vectors.
Thanks a lot.
Éric.
