A Taxonomy of Model-Based RL Algorithms

We’ll start this section with a disclaimer: it’s really quite hard to draw an accurate, all-encompassing taxonomy of algorithms in the Model-Based RL space, because the modularity of algorithms is not well-represented by a tree structure. So we will publish a series of related blogs to explain more Model-Based RL algorithms.

A non-exhaustive, but useful taxonomy of algorithms in modern Model-Based RL.

We simply divide Model-Based RL into two categories: Learn the Model and Given the Model.

• Learn the Model mainly focuses on how to build the environment model.

• Given the Model cares about how to utilize the learned model.

And we give some examples as shown in the figure above. There are links to algorithms in taxonomy.
