Thanks a lot for writing this tutorial, Andrej. Super clear, the next Feynman in the making here!

Interesting choice of language, maybe you could add little run buttons to the code snippets to try all the examples in the browser :-)

Thank you!

I'm a huge fan of interactive demos (see e.g. my ConvNetJS demos: http://cs.stanford.edu/people/karpathy/convnetjs/ ) because they help develop intuitions that solidify the material. And yes, that's partly why I chose Javascript; I'm definitely planning to add little demos of the gradients flowing around the circuit and so on. Coming soon! :)
