For some similarity/correlation measures, it is also possible to discard candidate pairs early, if a threshold for the resulting correlation is given. This could help to fight the quadratic nature of the problem. Looking for papers on similarity search might help. -s On 07.04.2015 15:19, Till

I don't know whether my ideas are much better than the cartesian product solution. As a matter of fact at some point we have to replicate the data to be able to compute the correlations in parallel. There are basically 3 ideas I had: 1. Broadcast U and V and simply compute the correlation for diff
