Overview of this book

With an increasing interest in AI around the world, deep learning has attracted a great deal of public attention. Every day, deep learning algorithms are used broadly across different industries. The book will give you all the practical information available on the subject, including the best practices, using real-world use cases. You will learn to recognize and extract information to increase predictive accuracy and optimize results. Starting with a quick recap of important machine learning concepts, the book will delve straight into deep learning principles using Sci-kit learn. Moving ahead, you will learn to use the latest open source libraries such as Theano, Keras, Google's TensorFlow, and H20. Use this guide to uncover the difficulties of pattern recognition, scaling data with greater accuracy and discussing deep learning algorithms and techniques. Whether you want to dive deeper into Deep Learning, or want to investigate how to get more out of this powerful technology, you’ll find everything inside.

Atari Breakout


Breakout is a classic Atari game originally released in 1976. The player controls a paddle and must use it to bounce a ball into the colored blocks at the top of the screen. Points are scored whenever a block is hit. If the ball travels down past the paddle off the bottom of the screen, the player loses a life. The game ends either when the all the blocks have been destroyed or if the player loses all three lives that he starts with:

Figure 8: Atari Breakout

Think about how much harder learning a game like Breakout is compared to the cart pole task we just looked at. For cart pole, if a bad move is made that leads to the pole tipping over, we will normally receive feedback within a couple of moves. In Breakout, such feedback is much rarer. If we position our paddle wrong, that can be because of 20 or more moves that went into positioning.

Before we go any further, let's create an agent that will play Breakout by selecting moves randomly. That way...
