I think it might not be entirely clear what this site represents. It's actually quick demo of ML services available on Azure. I think it uses Deep Learning and the power of it is to demonstrate that you can wire up something like this yourself without write a line of code for deep learning algorithms or even owning any servers at all for heavy GPU processing. I wish they had put code for this website on Github so people can tweak and spawn new versions.
