WebbThis motivates shaped rewards which are inserted at intermediate steps based on domain knowledge in order to introduce an inductive bias towards good solutions. For example, … Webb4 nov. 2024 · We introduce a simple and effective model-free method to learn from shaped distance-to-goal rewards on tasks where success depends on reaching a goal state. Our …
Webb1992; Peshkin et al. 2000) as the reward signal used to train agent policies has high noise due to other agents’ actions. Shaped rewards: Shaped rewards have been proposed to address the problem of multiagent credit assignment. Dif-ference rewards (DRs), computed as the difference between the system reward and a counterfactual reward when the ... Webb28 sep. 2024 · Keywords: Reinforcement Learning, Reward Shaping, Soft Policy Gradient. Abstract: Entropy regularization is a commonly used technique in reinforcement learning to improve exploration and cultivate a better pre-trained policy for later adaptation. Recent studies further show that the use of entropy regularization can smooth the optimization ...
WebbHowever, an important drawback of reward shaping is that agents sometimes learn to optimize the shaped reward instead of the true objective. In this report, we present a novel technique that we call action guidance that successfully trains agents to eventually optimize the true objective in games with sparse rewards yet does not lose the sampling … Webb12 okt. 2024 · This code provides an implementation of Sibling Rivalry and can be used to run the experiments presented in the paper. Experiments are run using PyTorch (1.3.0) and make reference to OpenAI Gym. In order to perform AntMaze experiments, you will need to have Mujoco installed (with a valid license). Running experiments

In this paper, we propose a shaped reward that includes the agent’s policy entropy into the reward function. In particular, the agent’s entropy at the next state is added to the immediate reward associated with the current state.
