Chapter 17. Beyond Model-Free – Imagination

In this chapter, we'll take a brief look at the model-based methods in Reinforcement Learning (RL) and reimplement the DeepMind model, which adds imagination to agents. Model-based methods allow us to decrease the amount of communications with the environment, by building a model of the environment and using it during the training.
