WebJul 29, 2024 · For DQN, exploration occurs with an epsilon-greedy mechanism. That means that with probability epsilon, a random Action will be chosen. The rest of the time, the Action with the best predicted reward will be used. It’s typical to start with a higher epsilon to encourage exploration, then reduce epsilon over time as the Agent hones in on a ...
