Webdecision process (MDP), how to properly design reward functions in the first place is a notori-ously difficult task. Well-known failures include reward hacking (Clark & Amodei, 2016; Rus-sell & Norvig, 2016), side effects (Krakovna et al., 2024), and the difficulty of learning when re- Web9 nov. 2024 · The sum of reward and discounted next state value is 14.0. The right action hits the wall, giving -1 reward and leaving the agent in the same state, which has a value of 16.0. The sum of reward and discounted next state value is 13.4. The down action leads here, giving no reward, but a next state value of 14.4. After discounting, this gives 13.
WebReward transition matrix, specified as a 3-D array, which determines how much reward the agent receives after performing an action in the environment. R has the same shape and size as state transition matrix T. The reward for moving from state s to state s' by performing action a is given by: WebMDP, while suggesting empirically that the sample complexity can be changed by a well specified potential. In this work, we use PBRS to construct ⇧-equivalent reward functions in the average reward setting (Section 2.4) and show that two reward functions related by a shaping potential can
