A JavaScript deep learning and reinforcement learning library

It&#x27;s useful only for predictions. Unless, GPU (Possibly with WebCL) support will appear, it will be impractical to use it for training.

I get why deep learning is nice but I just do not get the hype around reinforcement learning yet. RL seems great for things like training video game agents and have seen videos of this, but fail to understand where RL can be applied in the real world.<p>It reminds me a bit of genetic algorithms. GA is the &#x27;last resort&#x27; when you truly know nothing about how to model your problem.<p>What is the sweet spot for RL?

Interesting work ! Although I am not learning that :) What would be really interesting is a common interface for the browser and node, the former using this library, and the latter using a node extension communicating with tensorFlow... And on the user side a syntax EXACTLY similar to the Keras syntax. That - would be the bomb.

Does anyone know enough to lend some context here? I gather this works similarly to ConvNetJS, or solves some of the same problems. Does it go further, or work in a different way, or what?

Just curious: Where does the computation happen? Is it all Javascript?
