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.

Policy gradients in AlphaGo


For AlphaGo using policy gradients, the network was set up to play games against itself. It did so with a reward of 0 for every time step until the final one where the game is either won or lost, giving a reward of 1 or -1. This final reward is then applied to every time step in the network, and the network is trained using policy gradients in the same way as our Tic-tac-toe example. To prevent overfitting, games were played against a randomly selected previous version of the network. If the network constantly plays against itself, the risk is it could end up with some very niche strategies, which would not work against varied opponents, a local minima of sorts.

Building the initial supervised learning network that predicted the most likely moves by human players allowed AlphaGo to massively reduce the breadth of the search it needs to perform in MCTS. This allowed them to get much more accurate evaluation per rollout. The problem is that running a large many-layered...
