Webb10 sep. 2024 · Our results demonstrate that learning with shaped reward functions outperforms learning from scratch by a large margin. In contrast to neural networks , that are able to generalize to unseen tasks but require much training data, our reward shaping can be seen as the first step towards the final goal that aims to train an agent which is … Webbtopic of integrating the entropy into the reward function has not been investigated. 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. The addition of the how many champions are in tft pool
