@gbuesing could you update this with Tensor Flow, libraries mentioned in other comments and new libs that might have been released since last edit (if there's any you are aware of) ? Thanks!

As discussed via email with @gbuesing I forked this Gist and I'm trying to convert it to an Awesome List "Machine Learning with Ruby".
Everybody is welcome to collaborate!
