On each time step, the agent takes an action in a certain state and the environment emits a percept or perception, which is composed of a reward and an observation, which, in the case of fully-observable MDPs, is the next state (of the environment and the …
WebOct 13, 2024 · The main idea is to view RL as a joint optimization problem over the policy and experience: we simultaneously want to find both “good data” and a “good policy.” Intuitively, we expect that “good” data will (1) get high reward, (2) sufficiently explore the environment, and (3) be at least somewhat representative of our policy. WebThe following two sections outline the key features required for defining and solving an RL problem by learning a policy that automates decisions. ... Our algorithm builds on Double Q-learning, by taking the minimum value between a pair of critics to limit overestimation. We draw the connection between target networks and overestimation bias ...
