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”.

WebJan 29, 2024 · Sorted by: 1. The goal of reducing progressively epsilon parameter in a epsilon-greedy policy is to move from a more explorative policy to a more exploitative one. This step, only make sense when the agent has learnt something, i.e., when it has some knowledge to exploit. So, in short, you should start annealing after learning starts.
