Github user martinjaggi commented on the pull request:
    Hope you don't get me wrong, I was not at all proposing to fix a single scheme, neither
for serialization, or for the choice of sparse library. I was just suggesting that the existing
MLlib classification/regression code would be a nice benchmark to see how the several candidate
implementations perform in reality (these only need vectors, no matrices). No matter what
we will choose, serialization time will also play an important role in the end.
