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. WebOct 14, 2024 · In reinforcement learning, a policy that either follows a random policy with epsilon probability or a greedy policy otherwise. For example, if epsilon is 0.9, then the …
WebSep 21, 2024 · Follows an ε-greedy policy (epsilon greedy), which means the agent chooses the best value action with probability 1-ε, or a random one with probability ε. However, I made it so it couldn’t choose to bump into an external boundary -so it can’t try to go off-limits-, though that behavior could have been learned.
