Learning from human preference is a major breakthrough in RL. The algorithm was proposed by researchers at OpenAI and DeepMind. The idea behind the algorithm is to make the agent learn according to human feedback. Initially, the agents act randomly and then two video clips of the agent performing an action are given to a human. The human can inspect the video clips and tell the agent which video clip is better, that is, in which video the agent is performing the task better and will lead it to achieving the goal. Once this feedback is given, the agent will try to do the actions preferred by the human and set the reward accordingly. Designing reward functions is one of the major challenges in RL, so having human interaction with the agent directly helps us to overcome the challenge and also helps us to minimize the writing of complex goal functions...

Overview of this book
Reinforcement Learning (RL) is the trending and most promising branch of artificial intelligence. Hands-On Reinforcement learning with Python will help you master not only the basic reinforcement learning algorithms but also the advanced deep reinforcement learning algorithms.
The book starts with an introduction to Reinforcement Learning followed by OpenAI Gym, and TensorFlow. You will then explore various RL algorithms and concepts, such as Markov Decision Process, Monte Carlo methods, and dynamic programming, including value and policy iteration. This example-rich guide will introduce you to deep reinforcement learning algorithms, such as Dueling DQN, DRQN, A3C, PPO, and TRPO. You will also learn about imagination-augmented agents, learning from human preference, DQfD, HER, and many more of the recent advancements in reinforcement learning.
By the end of the book, you will have all the knowledge and experience needed to implement reinforcement learning and deep reinforcement learning in your projects, and you will be all set to enter the world of artificial intelligence.
