Overview of this book

Deep learning is a branch of machine learning algorithms based on learning multiple levels of abstraction. Neural networks, which are at the core of deep learning, are being used in predictive analytics, computer vision, natural language processing, time series forecasting, and to perform a myriad of other complex tasks. This book is conceived for developers, data analysts, machine learning practitioners and deep learning enthusiasts who want to build powerful, robust, and accurate predictive models with the power of TensorFlow, combined with other open source Python libraries. Throughout the book, you’ll learn how to develop deep learning applications for machine learning systems using Feedforward Neural Networks, Convolutional Neural Networks, Recurrent Neural Networks, Autoencoders, and Factorization Machines. Discover how to attain deep learning programming on GPU in a distributed way. You'll come away with an in-depth knowledge of machine learning techniques and the skills to apply them to real-world projects.

Summary

Many researchers believe that RL is the best shot we have of creating artificial general intelligence. It is an exciting field, with many unsolved challenges and huge potential. Although it can appear challenging at first, getting started in RL is actually not so difficult. In this chapter, we have described some basic principles of RL.

The main thing we have discussed is the Q-Learning algorithm. Its distinctive feature is the capacity to choose between immediate rewards and delayed rewards. Q-learning at its simplest uses tables to store data. This very quickly loses viability when the size of the state/action space of the system it is monitoring/controlling increases.

We can overcome this problem using a neural network as a function approximator that takes the state and action as input and outputs the corresponding Q-value.

Following this idea, we implemented a Q-learning neural network using the TensorFlow framework and the OpenAI Gym toolkit to win at the FrozenLake game.
