The problem is set up as a reinforcement learning problem, with a trial and error method. The environment is described using state_values
state_values (?)
, and the state_values
are changed by actions. The actions are determined by an algorithm, based on the current state_value
, in order to achieve a particular state_value
that is termed a Markov model. In an ideal case, the past state_values
does have an influence on future state_values
, but here, we assume that the current state_value
has all of the previous state_values
encoded. There are two types of state_values
; one is observable, and the other is non-observable. The model has to take non-observable state_values
into account, as well. That is called a Hidden Markov model.

Overview of this book
Reinforcement Learning (RL) is the trending and most promising branch of artificial intelligence. This Learning Path will help you master not only the basic reinforcement learning algorithms but also the advanced deep reinforcement learning algorithms.
The Learning Path starts with an introduction to RL followed by OpenAI Gym, and TensorFlow. You will then explore various RL algorithms, such as Markov Decision Process, Monte Carlo methods, and dynamic programming, including value and policy iteration. You'll also work on various datasets including image, text, and video. This example-rich guide will introduce you to deep RL algorithms, such as Dueling DQN, DRQN, A3C, PPO, and TRPO. You will gain experience in several domains, including gaming, image processing, and physical simulations. You'll explore TensorFlow and OpenAI Gym to implement algorithms that also predict stock prices, generate natural language, and even build other neural networks. You will also learn about imagination-augmented agents, learning from human preference, DQfD, HER, and many of the recent advancements in RL.
By the end of the Learning Path, you will have all the knowledge and experience needed to implement RL and deep RL in your projects, and you enter the world of artificial intelligence to solve various real-life problems.
