Keras Reinforcement Learning Projects

By: Giuseppe Ciaburro

Overview of this book

Reinforcement learning has evolved a lot in the last couple of years and proven to be a successful technique in building smart and intelligent AI networks. Keras Reinforcement Learning Projects installs human-level performance into your applications using algorithms and techniques of reinforcement learning, coupled with Keras, a faster experimental library. The book begins with getting you up and running with the concepts of reinforcement learning using Keras. You’ll learn how to simulate a random walk using Markov chains and select the best portfolio using dynamic programming (DP) and Python. You’ll also explore projects such as forecasting stock prices using Monte Carlo methods, delivering vehicle routing application using Temporal Distance (TD) learning algorithms, and balancing a Rotating Mechanical System using Markov decision processes. Once you’ve understood the basics, you’ll move on to Modeling of a Segway, running a robot control system using deep reinforcement learning, and building a handwritten digit recognition model in Python using an image dataset. Finally, you’ll excel in playing the board game Go with the help of Q-Learning and reinforcement learning algorithms. By the end of this book, you’ll not only have developed hands-on training on concepts, algorithms, and techniques of reinforcement learning but also be all set to explore the world of AI.

Continuous Balancing of a Rotating Mechanical System

The automatic control of a dynamic system—for example, a motor, an industrial plant, or a biological function, such as a heartbeat—aims to modify the behavior of the system that is to be controlled, or its outputs, through the manipulation of appropriate quantities of the inputs into the system.

Neural networks are exceptionally effective at generating results that meet the criteria for highly structured data. We could then represent our Q-function with a neural network, which takes the status and action as inputs and then outputs (gives) the corresponding Q-value. Deep reinforcement learning methods use deep neural networks to approximate the reinforcement learning components of the value function, policy, and model. In this chapter, we will learn how to use deep reinforcement learning methods for balancing a...
