@mengxr <https://github.com/mengxr> at the risk of adding to your
workload... I think (license issues aside since I suppose both Breeze and
MTJ are affected in the same way), that it would be great to get a sense of
MTJ performance (which should in theory be as good as or better than
Breeze).
One issue that came up with MLlib developers initially was that Breeze
performance suffered due to heavy implicit use / object creation. It would
be good to know if this is not the case anymore (ie if recent dev had fixed
this). If not, MTJ would be a good alternative (again, wrapped in a
lightweight DSL if we wish).
