Dmitriy Lyubimov commented on MAHOUT-1532:
------------------------------------------
sure. I actually kind of wanted to start on this myself a few times (e.g. it is
hugely useful in weighted als) but every time ended using our chol() stuff,
which is just a matter of sugar in this case. But yes this is hugely coherent
with our direction. Are you planning to use chol() for this or something else?
I think how people are doing it in major oos projects is by piggy-backing on UL
decomposition, which is probably the cheapest way o fdoing this. but we don't
have it so i guess it is ok to wrap it into a Cholesky or even qr.
