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.

Quick recap on reinforcement learning


We first encountered reinforcement learning in Chapter 1, Machine Learning – An Introduction, when we looked at the three different types of learning processes: supervised, unsupervised, and reinforcement. In reinforcement learning, an agent receives rewards within an environment. For example, the agent might be a mouse in a maze and the reward might be some food somewhere in that maze. Reinforcement learning can sometimes feel a bit like a supervised recurrent network problem. A network is given a series of data and must learn a response.

The key distinction that makes a task a reinforcement learning problem is that the responses the agent gives changes the data it receives in future time steps. If the mouse turns left instead of right at a T section of the maze, it changes what its next state would be. In contrast, supervised recurrent networks simply predict a series. The predictions they make do not influence the future values in the series.
