      This is how you implement a network in Chainer. Chainer, the original eager-first deep learning framework, has had this API since launch, in mid-2015. When PyTorch got started, it followed the Chainer template (in fact, the prototype of PyTorch was literally a fork of Chainer).pic.twitter.com/QjcBLdjfiB

      PyTorch autograd was inspired by Chainer. Keras was copied on Torch7 (transcribed from Lua to Python). Torch7 was very much inspired by Lush (transcribed from Lisp to Lua). But every time, some new twists are added.

      The only thing Keras took from Torch7 is the name of the Sequential class. Checking out early Keras versions demonstrates they have virtually nothing in common. The promo line "in the spirit of Torch" was only meant as "it's simple/minimalist". Sklearn was a far bigger influence.

      From Sklearn, I borrowed "fit", but more generally best practices around usability. There were also many innovations from day one (RNN layers...) and that we added later (callbacks, functional API).

          I’d rather everyone borrow and keep naming consistent where possible. :)

          And no one mentions the eager-first autograd from cuv/cuvnet from ~2011 in c++ and python by me and @temporaer :( not that I'm surprised lol we didn't advertise and at least the versions I worked on weren't that great.

          When you say you ‚borrowed‘... when are you planing to give it back?! 😉
