Cool concept, with some issues – mobileML Review

I love the idea here. It's a sort of neural network mini-lab, and could be great for people like me who want to get into AI/machine learning/data-driven app development. Unfortunately, I find the interface a bit clunky, and there seems to be a frequent glitch that causes some wights to become "NaN" (not a number). I'd like to see the app further developed.
