In order to increase the frequency of such observations, \"potential-based reward shaping\" (PBRS) has been proposed as a method of providing a more dense reward signal while leaving the optimal policy invariant. However, the required \"potential function\" must be carefully designed with task-dependent knowledge to not deter training performance. In this work, we propose a \"bootstrapped\" method of reward shaping, termed BSRS, in which the agent's current estimate of t","authors_text":"Jacob Adamczyk, Rahul V.
