I've been meaning to get them everywhere. The word "brain" is better translated as "neural-network" in english. r~

I've been meaning to get them everywhere. Yes, but they have been spread to everywhere. Should we just make bfloat16 different or remove all other references? > The word "brain" is better translated as "neural-network" in english.

Otherwise, let's just make bfloat16 different. >> The word "brain" is better translated as "neural-network" in english. > Do you mean the comment here should be > > +/* > + * Software neural-network floating-point types > + */ Yes, thanks. r~
