WebMay 24, 2024 · The above is essentially one of the main properties of on-policy methods. An on-policy method tries to improve the policy that is currently running the trials, meanwhile an off-policy method tries to improve a different policy than the one running the trials. Now with that said, we need to formalize “not too greedy”. WebBy customizing a Q-Learning algorithm that adopts an epsilon-greedy policy, we can solve this re-formulated reinforcement learning problem. Extensive computer-based simulation results demonstrate that the proposed reinforcement learning algorithm outperforms the existing methods in terms of transmission time, buffer overflow, and effective ...
