WebMar 31, 2024 · Episodic or Continuing tasks A task is an instance of a Reinforcement Learning problem. We can have two types of tasks: episodic and continuous. Episodic task In this case, we have a starting point and an ending point (a terminal state). This creates an episode: a list of States, Actions, Rewards, and New States. WebNov 20, 2024 · If the intrinsic rewards were episodic, these actions might have ended the game, thus ending the rewards. Extrinsic rewards are counted over an entire episode until the agent dies. Using non-episodic rewards might cause the agent to “hack” the game. For example, by finding easy and quick rewards and then killing itself.

WebOne common form of implicit MDP model is an episodic environment simulator that can be started from an initial state and yields a subsequent state and reward every time it receives an action input. In this manner, trajectories of states, actions, and rewards, often called episodes may be produced.
