The Little Book of Deep Learning

It's a pretty short book designed to provide a strong conceptual grounding in the most import ideas in deep learning, starting with an intro to ML. The book posted by the OP appears to be a little more oriented towards the math and people who have a strong grasp of CS theory. I am definitely going to read through it!
I was considering going even smaller and cuter with my actual print book, but ended up with a "pocket book" format that's 5.25" x 8" (13.3cm x 20.2cm) and about 160 pages total. This book seems to get the smallness part down pretty well.
I actually considered the exact same title (The Little Book of Deep Learning) when I started out!
Multiplied by the risk I won't actually have time to read it.
