@dbtsai 1) Could you elaborate on what kind of optimizations did you do?
Probably, they could be applied to the broader MLlib, which is beneficial. 2)
Do you know the reason why our ANN implementation worked faster than the MLOR
you shared? This could also be interesting in terms of MLlib optimization. 3)
Did you mean fitting a n-th degree polynom instead of a linear function? Thanks
for the link, it seems very interesting!
