Overview of this book

This Learning Path is your complete guide to quickly getting to grips with popular machine learning algorithms. You'll be introduced to the most widely used algorithms in supervised, unsupervised, and semi-supervised machine learning, and learn how to use them in the best possible manner. Ranging from Bayesian models to the MCMC algorithm to Hidden Markov models, this Learning Path will teach you how to extract features from your dataset and perform dimensionality reduction by making use of Python-based libraries. You'll bring the use of TensorFlow and Keras to build deep learning models, using concepts such as transfer learning, generative adversarial networks, and deep reinforcement learning. Next, you'll learn the advanced features of TensorFlow1.x, such as distributed TensorFlow with TF clusters, deploy production models with TensorFlow Serving. You'll implement different techniques related to object classification, object detection, image segmentation, and more. By the end of this Learning Path, you'll have obtained in-depth knowledge of TensorFlow, making you the go-to person for solving artificial intelligence problems This Learning Path includes content from the following Packt products: • Mastering Machine Learning Algorithms by Giuseppe Bonaccorso • Mastering TensorFlow 1.x by Armando Fandango • Deep Learning for Computer Vision by Rajalingappaa Shanmugamani

Chapter 15. Deep Reinforcement Learning

Reinforcement learning is a form of learning in which a software agent observes the environment and takes actions so as to maximize its rewards from the environment, as depicted in the following diagram: 

This metaphor can be used to represent real-life situations such as the following:

  • A stock trading agent observes the trade information, news, analysis, and other form information, and takes actions to buy or sell trades so as to maximize the reward in the form of short-term profit or long-term profit.
  • An insurance agent observes the information about the customer and then takes action to define the amount of insurance premium, so as to maximize the profit and minimize the risk.
  • A humanoid robot observes the environment and then takes action, such as walking, running, or picking up objects, so as to maximize the reward in terms of the goal achieved.

Reinforcement learning has been successfully applied to many applications such as advertising optimization...
