Sort of.
I may be misunderstanding the question.
If you take a random orthogonal projection, then distances will be preserved
within a reasonably small epsilon to reasonably high probability.
Mathematically, if you take a random matrix \Omega which is tall and skinny
and do a QR decomposition:

Does this all translate to doing high-dimensional distance with random
projection? Project each vector to one dimension and subtract? This sounds
like a really useful distance measure.

I think that your meaning is roughly clear.
You are right that we don't have a very universal framework for this. It
would be good to have such a thing.
Would you be interested helping to construct such a framework?

Hi!
I want to develope new classifier in mahout, but i noticed, that probably
there is any pattern (schema) for global sight for classificators. This
mean: i probably must write own data loader, i didn't find any abstract
training class and any test class and so on. I think it could be great if we
