Model-Based RL

Advanced

RL using learned or known environment models.

Model-based reinforcement learning is like having a map while exploring a new city. Instead of wandering around aimlessly, you can look at the map to plan your route and make better decisions about where to go next. In this type of learning, an AI agent first learns how the environment works—like...
