Are we trying to use double precision? Shouldn't be needed for nnets. The trajectory seems to be going to smaller and smaller types actually (i.e. nirvana's 16bit ultra fast impl)

pavanky commented 8 years ago

It should not be using double precision. Which version of ArrayFire are you using ?

jramapuram commented 8 years ago

3.02

pavanky commented 8 years ago

~~Can you try this with our devel branch ?~~

pavanky commented 8 years ago

This seems to be a problem in the main arrayfire library. I pushed a fix to this library that works around the issue.

Nice, ty Ill try it with the tip
