- DRQN makes use of recurrent neural network (RNN) where DQN makes use of vanilla neural network.
- DQN is not used applied when the MDP is partially observable.
- Refer section Doom with DRQN.
- DARQN makes use of attention mechanism unlike DRQN.
- DARQN is used to understand and focus on particular area of game screen which is more important.
- Soft and hard attention.
- We set living reward to 0 which the agent does for each move, even though the move is not useful.

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.
