I'm currently working through "Deep Learning: A Practitioner's Approach" by Adam Gibson and Josh Patterson. Its a couple of years old but seems like a good book, and I'm certainly learning a lot. It doesn't consider some of the newer tooling, like TensorFlow, but the fundamentals plus a decent amount of theory are all covered.
What makes you say the book is 2 years old? Its publication date is Aug 1, 2017. It's based on Deeplearning4J and ND4J rather than TF, but that doesn't date it necessarily.
You're right, it is August 2017. I bought it from Amazon UK and they list the date as November 2015 [1] for some reason. I should have checked the book before posting. I've flagged the error with Amazon UK.
