Overview of this book

Start your journey into reinforcement learning (RL) and reward yourself with the third edition of Deep Reinforcement Learning Hands-On. This book takes you through the basics of RL to more advanced concepts with the help of various applications, including game playing, discrete optimization, stock trading, and web browser navigation. By walking you through landmark research papers in the field, this deep RL book will equip you with practical knowledge of RL and the theoretical foundation to understand and implement most modern RL papers. The book retains its approach of providing concise and easy-to-follow explanations from the previous editions. You'll work through practical and diverse examples, from grid environments and games to stock trading and RL agents in web environments, to give you a well-rounded understanding of RL, its capabilities, and its use cases. You'll learn about key topics, such as deep Q-networks (DQNs), policy gradient methods, continuous control problems, and highly scalable, non-gradient methods. If you want to learn about RL through a practical approach using OpenAI Gym and PyTorch, concise explanations, and the incremental development of topics, then Deep Reinforcement Learning Hands-On, Third Edition, is your ideal companion *Email sign-up and proof of purchase required

Adding text description

As a first step to improve our clicker agent, we’ll add the text description of the problem into the model. I have already mentioned that some problems contain vital information that is provided in a text description, like the index of tabs that need to be clicked or the list of entries that the agent needs to check. The same information is shown at the top of the image observation, but pixels are not always the best representation of simple text.

To take this text into account, we need to extend our model’s input from an image only to an image and text data. We worked with text in the previous chapter, so a recurrent neural network (RNN) is quite an obvious choice (maybe not the best for such a toy problem, but it is flexible and scalable).

Implementation

In this section, we will just focus on the most important points of the implementation. You will find the whole code in the Chapter16/wob_click_mm_train.py module...
