While people tends to use machine learning and regressions models more and more
it is interesting to have some general n-dim indexing with kNN,
but I think it is different problem and should be solved in a different way.
I think one of the issues here is it's not very clear to someone without
a good amount of ML knowledge how these things relate. I hear "box' and
'cube' and think it's just a 2D vs 3D issue, and intarray isn't even on
the radar.
Maybe what's needed are actual vector and matrix types?
In any case, if you've got a good reason why box and cube should stay
separate then further discussion should happen in another thread.
BTW, if you haven't seen it, take a look at http://madlib.apache.org/
