9 Going Pro with Artificial Brains – Deep Q-Learning

This next AI model is fantastic, because it is the first AI model that is really inspired by human intelligence. I hope you're ready to go pro on the next exciting step in your AI journey; this book is not only a crash course on AI, but also an introduction to deep learning.

Today, some of the top AI models integrate deep learning. They form a new branch of AI called deep Reinforcement Learning. The model we'll cover in this chapter belongs to that branch, and is called deep Q-learning. You already know what Q-learning is all about, but you might not know anything about deep learning and Artificial Neural Networks (ANNs); we'll start with them. Of course, if you are an expert in deep learning, ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
