I have two engineering degrees and studied neural networks in college. He cuts down about 3 months worth of math to a couple of lines of code in such a way that makes it make sense AND is productive. It may just be that his teaching style matches my learning style really well, but I'm enjoying going through it.

I'd second this. I'm not a "math person" so to speak, and they provide a great education that doesn't dip too deep into the math.
