Training and Simulation
Train and simulate reinforcement learning agents
During training, the agent continuously updates its parameters to learn the optimal policy for a given environment. During simulation, the agent receives observations and a reward from the environment, and returns an action to the environment without updating its parameters.
Reinforcement Learning Toolbox™ provides functions for training agents and validating the training results through simulation. For an introduction to training and simulating agents, see Train Reinforcement Learning Agents.
